For Good Measure: Baking with Gluten-Free Blends, Whole Wheat Flour, Sourdough and at Challah Bakes

By: Rabbi Dovid Heber

Spring 2024

Once upon a time, baking a loaf of bread was simple. Today, when gluten-free blends and processed whole wheat flour are found in many homes, that is no longer the case. Baking with sourdough starters and group baking at “challah bakes” have also become popular. The halachos involved are complex and bear examination.

Let’s begin with a review of the measurements necessary for mitzvos related to regular wheat flour.[1]

Mitzvos Involving Wheat Flour

► Separating Challah (hafrashas challah) Without a Bracha – One should separate challah without a bracha when kneading a dough that contains at least 8 ⅔ cups of wheat flour (on average 2.6 lbs.).[2]

► Separating Challah With a Bracha – There are differences of opinion as to how much flour is needed to recite a bracha. Some individuals do so when kneading at least 12 ¼ cups of flour (slightly more than 3 ⅔ lbs.).[3] Others only do so when kneading at least 5 lbs. of […]

Producción de Carne Kasher: Shechita Flies South

By: Rabbi Zvi Holland

Spring 2024

From time immemorial, no matter where in the far-flung Diaspora, the presence of a Jewish community has always meant that there was shechita in proximity. The position of community shochet was one of a klei kodesh and the shochtim of a community were subject to the supreme jurisdiction of the local rav and/or Beis Din.

Here, in the U.S., it was no different. On November 15, 1660, a man named Asser (Asher) Levy acquired a license to serve as the first kosher butcher in the small Dutch-controlled hamlet of Nieuw Amsterdam – now better known as New York City.[1] Ever since, maintaining a reliable supply of kosher beef has been an integral part of Jewish communal life in the U.S. Previous Kashrus Kurrents articles have offered a glimpse into the challenges shechita has faced on these shores and the changes to the way kosher meat is supplied […]

Acids in Digestion

By: Rabbi Tzvi Rosen

Spring 2024

When my father z”l went to pharmacy school at George Washington University, his course of study had a heavy concentration of chemistry. His background in chemistry proved extremely useful in his forty-year career as an examiner in the U.S. Patent Office. On his workbench, he had shoe boxes with all his pharmacological paraphernalia: Bunsen burners, beakers, and little vials of litmus paper. As a child, I remember my fascination with watching the red litmus paper turn blue when dipped into a base and the blue litmus paper turn red when dipped into an acid. These were literal litmus tests, a term which over time has crept into everyday language to denote a means of determining an outcome.

Although the world of industrial kashrus may not require the deep analysis found in chemistry textbooks, it behooves kashrus administrators and mashgichim to have a working knowledge of chemical compositions and formulations. Solid […]

Yoshon: To Keep or Not to Keep

By: Rabbi Mordechai Frankel

Winter 2024

The Gemara seems to conclude that the prohibition on the consumption of chodosh applies worldwide.[1] However, many shomrei mitzvos outside Eretz Yisrael do not restrict themselves to eating only yoshon grain. Various reasons have been proposed:

► The Rema says that people rely on the fact that for any particular product that are two uncertainties. It is possible that there the food was made from a previous year’s wheat crop and is yoshon. It is also possible that this year’s crop took root before 16 Nissan and is yoshon. As there are two areas of doubt – a sfek sfeika – one can be lenient.[2] Others disagree and maintain that there is only one uncertainty here, whether the grain is chodosh or yoshon, and one should be stringent.[3]

► The Bach says that the prohibition does not apply to grain produced in a field owned […]

What’s “New” in Chodosh

By: Rabbi Sholom Tendler

Winter 2024

The Torah states[1] that chodosh (new) crops of the five grains may not be eaten until after the second day of Pesach (outside of Israel, not until the third day).[2] Thus, grain harvested in the summer of 2023 would not be allowed until Pesach 2024. On the other hand, yoshon (old) crops, which were harvested in the summer of 2022, became permitted after Pesach 2023. Grain planted at least two weeks or more before Pesach are permitted upon harvest, since they took root before Pesach.[3]

Outside of Israel, there are various customs based on numerous sources as to whether or not one needs to be stringent about using only yoshon products (see Rabbi Mordechai Frankel’s article in this issue). Each person should consult their rav for guidance. In Israel, however, these leniencies do not apply. Therefore, any product from Israel bearing a reliable kosher […]

Controlling Your Temper

By: Rabbi Tzvi Rosen

Winter 2024

The baalei mussar, our guides in ethical character development, have instructed us that in order to develop and refine one’s behavior, one has to control one’s temper.

Controlling temper in manufacturing is a means to refine and improve the quality of the product in question. When steel is tempered, the resiliency of the steel is improved through the process of heating and cooling. When chocolate is tempered, through a similar process of heating and cooling (albeit at a much lower temperature), the chocolate acquires a lustrous, luxurious sheen, impervious to changes in color.

Likewise, tempering grain for milling improves the grain so that the final product – wheat flour – is rendered white and fluffy. The source of this final product is the humble wheat kernel.

A wheat kernel or berry is the seed of the wheat plant and is comprised of three edible parts: the nutritious bran wrapped protectively around the […]

Toveling Utensils in a Lake or River

By: Rabbi Mordechai Frankel

Summer 2013

Q: I am traveling, and there is no keilim mikvah in this area. May I tovel new utensils in a lake or river?

A: Metal, glass and glazed ceramic utensils which are purchased from a non-Jew and are used in the preparation and consumption of food require tevila before use.[1] A person may tovel utensils in “spring water” – water that flows naturally from under the ground. If a river has such water as its source, he can tovel his utensils in the river.[2] The river must contain at least forty se’ah of water, which calculates as 175 gallons of water.[3] An ocean or sea is halachically considered to be “spring water.”[4] Therefore, a person may tovel utensils in an ocean, sea, or river which has such water as its source. However, regarding a river which has “spring water” as its source, […]

The Kashrus of Tea—With No Strings Attached!

By: Rabbi Baruch Beyer

Summer 2013

Americans generally do not drink as much tea as the rest of the world. This may have something to do with a certain party they had in Boston a while back. That being the case, you might be surprised to learn that tea is second only to water in worldwide beverage consumption. In fact, some estimates place tea consumption in the billions of cups daily. That’s a lot of tea. However, with recent health benefits being ascribed to tea, its popularity in this country is definitely on the rise. In this article we will explore the world of tea vis-a-vis kashrus and halacha. First, a little background is in order.

BACKGROUND

Tea is a processed leaf. It is grown on a tea tree which, if allowed to grow wild, would reach 30 or more feet in height. On tea plantations, the main trunk of the seedlings is cut to produce a […]

The Knead to Know: The Rise of Sourdough

By: Rabbi Tzvi Rosen

Fall 2023

We are all familiar with the Torah’s directive to rid our homes of chometz in order to prepare for Pesach. The Torah uses two terms when instructing us in the cleaning process: chometz and se’or.

Ask any talmid or talmida: “What is chometz,” and you will get a very erudite response. Ask the next question: “What is se’or,” and seven out of ten will shrug and say, “I dunno,” while the other three might venture, “Sourdough?” When you follow up and ask them to define sourdough, most – if not all – will say, “I dunno!”

Today, more and more homes are seeing sourdough boules find their way into their bread baskets. With its “rise” in popularity, it is only natural that we look into this new trend and ask, “Ma nishtana sourdough bread from its conventional counterpart? Are there halachic and practical differences?”

Shemita After Shemita: It’s Not Over Yet!

By: Rabbi Ahron Haskel

Fall 2023

There are those who think that whatever comes from Israel is kosher and who are not aware of the many issues associated with goods that are produced in Israel, be they concerns of orla, terumos, maasros – or Shemita. And they believe that once the Shemita year ends, Shemita issues are a thing of the past.

The Shemita year ended more than a year ago. To many of us, it already seems like a distant memory, a topic that we will next revisit in roughly five years, when we prepare for Shemita of 5789. But the truth is that Shemita of 5782 is still very relevant. It is important to remember this because our brethren in Chutz La’aretz are less aware of mitzvos hatluyos ba’aretz.[1] Since produce in the Diaspora are not subject to these laws, there is less awareness of Shemita repercussions.

We are currently in a period […]

When It’s “Not Kosher” to Eat Kosher: The Halachos of the Fast Days

By: Rabbi Dovid Heber

Fall 2023

With the impending arrival of Tzom Gedalya and Yom Kippur, now is a good time for a halachic review of the six ta’aneisim that are incorporated into the Jewish calendar.[1] In addition to the aforementioned, we fast on Asara B’Teves, Ta’anis Esther, Shiva Asar B’Tamuz and Tisha B’Av. The halachos apply to males from the age of thirteen and females from the age of twelve.[2]

Timing Is Everything: When the Fasts Begin and End

Yom Kippur[3] and Tisha B’Av[4] begin at sunset. If one wants to eat after the seudas hamafsekes, one should state before the end of the seudah that he wants to do so. Having this in mind before Birchas Hamazon is also enough.

The other fasts begin at alos hashachar (dawn).[5] On those days, if one wants to arise[6] before dawn and eat, he should go to […]

Starbucks, Dunkin’ & Other Coffee Shops: Getting Your Caffeine Boost In-Town and On-the-Road

By: Rabbi Baruch Beyer

Summer 2023

The STAR-K Hotline receives no end of calls from coffee heads who dote on their daily cup of joe, whether from a local Starbucks or a Dunkin’ on the road. Recent changes in Starbucks’ company policy vis-à-vis kosher have further elevated the confusion for the kosher coffee connoisseur. Let’s dive in to clear out some of the haze.

Unflavored roasted coffee beans, whole and ground, are considered kosher without a hechsher. Bearing this in mind, buying a cup of unflavored regular or decaf coffee should not present any kashrus issues. Some coffee vendors, however, sell kosher and non-kosher items, like bacon and ham-filled sandwiches. The keilim used for coffee and the treif items are at times washed together, causing blios (absorbed tastes) from the treif utensil to enter the coffee equipment.

For example, at Starbucks, it’s been established that the brew basket that holds the coffee grounds while the coffee is […]

Cool Drinks for a Hot Summer Day: A Review

By: Rabbi Tzvi Rosen

Summer 2023

Each summer the STAR-K Hotline fields hundreds of questions from concerned kosher consumers, thirsty to know: Is my Slurpee kosher? Do smart waters need a hechsher? What are the concerns with shaved ice and sno-cone stands? We stand ready to quench your thirst for information!

Carbonated Beverages

Carbonated beverages involve two major processes: compounding the flavor bases to create the flavor, and bottling the finished product when the sweetening agents, carbonation and water are added.

Soft drinks are compounded into soda flavor bases at one of three locations: the bottling facility, a separate technical center dedicated to blending soda emulsions, or an outside flavor house. In the latter case, the flavor house will create custom emulsions with specifications laid out by the soft drink company.

Regardless of the location, the most intensive part of kosher soft drink certification entails compounding, since this is when the kashrus of the flavors, colors, oils and blending […]

Insights From the Institute: The Mesorah on Duck Eggs

By: Rabbi Mordechai Frankel

Summer 2023

Q: My local farmer’s market sells duck eggs. Can I assume that they are kosher?

A: Although the Torah lists twenty-four non-kosher species of birds, we no longer know precisely to which species the Torah is referring.[1] The Gemara provides alternative ways to ascertain whether a bird is kosher, but notes an instance in which a mistake in identification transpired.[2] For this reason, Rashi states that we do not rely on the Gemara’s criteria, and we eat only the few species of birds for which we have a mesorah (oral tradition) that attests to their kosher status.[3]

The Baal Ha’maor, one of the Rishonim, maintains that he has a tradition that all birds with wide feet and a wide beak – those more or less resembling a goose – are deemed kosher if they meet the Gemara’s criteria.[4] The Shulchan Aruch […]

Why the “D” in Non-Dairy?

By: Rabbi Tzvi Rosen

Summer 2023

The Merriam-Webster Dictionary offers the following definitions for the noun dairy: the department of farming or of a farm that is concerned with the production of milk, butter, and cheese; milk from a cow or other domestic animal (such as a goat); and food (such as ice cream, cheese, or yogurt) made primarily of or from milk.

Today, a dairy is far more than a producer of milk products. If we were to explore a modern-day dairy, a far more accurate definition would be: an establishment that processes milk; milk products, such as ice cream, buttermilk and yogurt shakes; non-dairy alternative frozen desserts; non-dairy novelties, such as ices and popsicles; and non-dairy beverages, such as juices, fruit punch and tea.

Unquestionably, liquid milk production is the bread and butter of a successful dairy plant. Juices and teas are suitable side dishes and, of course, the pièce de resistance is ice cream […]

Putting the New in Shehecheyanu

By: Rabbi Chananya Jacobson

Kashrus Kurrents, Spring 2023

Shehecheyanu is a bracha
that is said on special occasions, which the Gemara defines as something that
only “happens from time to time.”[1] We
say Shehecheyanu not only on religious occasions, such as the Yamim
Tovim, but also to express our appreciation for new experiences and pleasures.
Unlike the obligatory Shehecheyanus said on the zmanim and their mitzvos,[2] these
brachos are voluntary; perhaps that is why people are not always careful to say
them in every situation that would warrant it.[3]

New Fruit

The Shulchan Aruch writes, “One who sees a fruit which grows anew every year says Shehecheyanu, even if he sees it in his friend’s hand, or while still on the tree.”[4] In other words, the primary motivator for the bracha should be the sight of the new fruit. This is indeed how the halacha was originally codified by the Rambam.[5] However, the Mechaber concludes, “The custom is to […]

Mashke Goes Mainstream

By: Rabbi Zvi Holland

Kashrus Kurrents, Spring 2023

In the last year, STAR-K certified a host of iconic brands in the
alcoholic beverages category from almost all the way around the globe: from the
green pastures of Kentucky, to the shores of Baltimore’s Inner Harbor; crossing
the Atlantic Ocean to the Emerald Isle, Ireland; and completing the journey in Italy.
These newly kosher-certified brands include selected products from Baltimore’s
own Sagamore spirits; Wild Turkey and Skyy Vodka; Bailey’s Irish Cream Original
(STAR-D Dairy, non-cholov Yisroel); and Frangelico, all of whom have joined
the STAR-K Family just this year.

Kosher certification for spirits addresses a number of serious issues that have cropped up, as the industry has globalized and consolidated operations. Growing use of additives and processing aids that need certification – such as flavor chemicals, glycerin and the use of shared transportation bottling lines with dairy and non-kosher products – makes kosher certification more and more relevant, even in product categories that […]

Who Has Whom…Over the Barrel?

By: Rabbi Tzvi Rosen

Kashrus Kurrents, Spring 2023

The immortal words of Koheles, “l’kol zman va’eis” – there
is a time and a place for everything – rings true in all of life’s twists and turns
and is certainly relevant in the world of kashrus and kashrus standards. Kosher
food certification has grown exponentially, and standards have improved with
age. Who would have dreamed that pas Yisroel, bishul Yisroel, and
cholov Yisroel would be available to the wider kosher marketplace?

Forty years ago, a can of tuna with bishul Yisroel and hashgacha
temidis was a rare commodity. Many a yeshiva would resort to stam cholov
when cholov Yisroel wasn’t available, something that would be
unheard of half a century later. Yoshon was an anomaly, except for the
meticulous few; today, yoshon is a kosher household term and it
continues to proliferate.

These amazing developments across a variety of industries are a
testament to the tireless diligence of kashrusagencies who strive to
provide the kosher consumer with the finest […]

STAR-K Goes to College: An Interview with Rabbi Mayer Kurcfeld

Kashrus Kurrents, Spring 2023

Some of the top colleges in the U.S. boast a 10-25 percent Jewish
student population. In 2022, Jewish students were well-represented at all eight
Ivy League schools, with Columbia leading the way at 24%, followed by Brown
(19%), Cornell and UPenn (tied at17%), and Yale (13%).[1] The
continually increasing number of kosher and other Jewish amenities on the American
college campus mirror these statistics – and act as magnets to attract Jewish
students. For some, STAR-K’s presence on campus offers a first – and sometimes
only – taste of Yiddishkeit.

Rabbi Mayer
Kurcfeld, a STAR-K kashrus administrator, has been engineering and overseeing the
agency’s many certified on-campus facilities since 1999, custom-designing those
that were not pre-existing. I asked him to describe the kashruschallenges
of certifying the ever-evolving college campus dining platform.

U.S. colleges and universities are certified by STAR-K?

University, Franklin & Marshall College, Ithaca College, Johns Hopkins
University, Muhlenberg College, […]

Wanting the Best for Our Children: Meeting Kashrus Challenges in Yeshiva, Camp, and Day School Kitchens

By: Rabbi Dovid Heber

Kashrus Kurrents, Winter 2023

Kashrus has come a long way over the
past fifty years. Agencies ensure the highest standards of kashrus in factories
and food establishments worldwide, with experts in halacha, food technology, equipment,
and ingredients. Consumers have been trained to know which products are acceptable
and how to maintain a kosher kitchen l’mehadrin.

However, one area of kashrus that
has received far less attention – even throughout the past several decades of unprecedented
kashrus growth – is kashrus in our schools. This is due to several inaccurate reasons,
including the following:

Myth #1: “Religious teachers are in
the building all day and they oversee kashrus and everyone is careful.” Realistically, this is not the case.
Unless a teacher is told to “be on top” of the situation, only minimal oversight
will typically occur. Unfortunately, not everyone is familiar with the intricacies
of kashrus, and without guidelines a lot can go wrong.

Myth #2: “Unlike a for-profit eating
establishment, which obviously needs oversight […]

Rice: Nature’s Answer To Hashem’s Blessings

By: Rabbi Tzvi Rosen

Kashrus Kurrents, Winter 2023

It has been touted as nature’s most versatile food. There is no single
grain that feeds more people around the globe and, because it is free of gluten
and allergens, can be tolerated by most everyone. It is the most widely
consumed staple for over half of the world’s human population.[1]

When the Gemara in Brachos discusses the brachos that
are made before and after eating this versatile grain, the mnemonic used to
remember the poskim’s conclusion is אמן: Orez, Mezonos, Nefashos. The grain we are discussing is
Oryza sativa, which the Gemara refers to as orez.[2] We
know it, simply, as rice.

There are over 7,000 varieties of rice grown worldwide. Rice is mostly consumed in the Asian regions from Japan in the east
to Pakistan in the west and, after sugarcane and maize, is the third most
produced agricultural crop in the world.[3] China
and India account for more than half […]

Everything You Need to Know About Storing and Checking Brown Rice

By: Rabbi Sholom Tendler

Kashrus Kurrents, Winter 2023

Brown rice is a whole natural grain that goes through minimal
processing. It is therefore more susceptible to infestation concerns than
grains that are more processed.

Whole unprocessed grains can have microscopic eggs attached to
them. If left in improper conditions, like warm or humid environments, they can
hatch and may pose a seemingly ‘sudden’ infestation, even in well-sealed
containers. Insects like beetles and weevils found in packages of brown rice
are known as ‘pantry pests’ and are the result of improper storage. This can
happen at any point in the supply chain, from the initial processing or packing
plant to the kitchen pantry.

To minimize the risk of infestation, STAR-K recommends brown
rice be checked prior to use using the method outlined below. Anyone who wishes
to stock up on large quantities of brown rice (or any grains) should first
check the rice, then store it for at least 96 hours at below freezing
temperatures. This will effectively […]

Charting the Course of Shemita

By: Rabbi Sholom Tendler

Kashrus Kurrents, Summer 2022

Eretz Yisroel is known worldwide for its high-quality produce.
During non-Shemita years, a wide selection of Israeli produce items – among them: carrots, citrus fruits,
herbs, peppers, and radishes – are exported to North American markets. The
typical concern is to ensure that
proper terumos and maasros are taken. During Shemita, terumos
and maasros are not typically applicable[1],
but there is significant concern that the produce may be from Shemita.
If someone purchased Israeli produce from Shemita and paid cash (as
opposed to by check
or credit card), returning it to the store may also potentially violate the
prohibition of doing business with Shemita produce. If this happens by mistake, a rav
should be consulted.[2]

While it can be assumed that all vegetables currently on the
market are from the Shemita year,not all Israeli fruits yet on the market are from
the Shemita year. The Halacha is that the Shemita status of
fruits is determined by when they […]

A Consumer’s Guide to Shevi’is Produce

By: Rabbi Mordechai Frankel

Kashrus Kurrents, Summer 2022

The
Torah commands us to refrain from working the land of Eretz Yisroel during Shemita.
The possuk states that a person may work the land of Eretz Yisroel for
six consecutive years but must allow it to lie fallow during the Shevi’is
(seventh) year.[1]
This seventh year is known as Shemita.[2] The mitzvah applies to both
men and women.[3]
Even though time-bound positive commandments generally do not apply to women,
this mitzvah is an
exception and is equally incumbent upon them.[4]

The
Torah also commands us to sanctify every fiftieth year as Yovel.[5] However,
the Yovel year does not occur nowadays. This is due to the fact that Yovel
is sanctified only when the majority of Jews live in Eretz Yisroel.[6] By
the time of the destruction of the first Beis Hamikdash, the majority of Jews
had been exiled from Eretz Yisroel and Yovel no longer occurred. Although
Jews returned to Eretz Yisroel at […]

A Profile of Courage and Inspiration: A Trip To a Yerushalmi Otzar Beis Din

By: Rabbi Tzvi Rosen

Kashrus Kurrents, Summer 2022

Anyone
who has had the opportunity to visit Yerushalayim Ir HaKodesh, as
I recently did, will tell you that a must-see experience is a trip to the Geula
neighborhood on Erev Shabbos.

Rechov
Malchai Yisroel could very well be dubbed the commercial heart of the Chareidi community.
The stores pulsate with energy and electricity, while the streets teem with
traffic tie-ups, both on and off the sidewalks. It could be termed a
businessman’s dream or nightmare, depending on one’s ability to handle the
sheer crush of consumers. The side streets, on the other hand, are a labyrinth
of quiet residential apartments. One such quiet street is Rechov Yonah.

For six
out of seven years, the Stern family’s mirpeset (balcony) on Rechov
Yonah looks like any other mirpeset, but this year is not like the
others. During this year, shnas haShemita, the Stern’s mirpeset undergoes
an amazing transformation. Welcome to the Otzar of Bnei Brak – Jerusalem
Branch!

In brief,

The Otzar Beis Din: Shemita’s Treasure Trove

Rabbi Yirmiyohu Kaganoff, Rav & Rosh Kollel in Neve Yaakov, Jerusalem | Guest Contributor

Kashrus Kurrents, Summer 2022

An Otzar Beis Din is literally ‘a storehouse operated
by Beis Din.’ Why would Beis Din operate a warehouse? Before
explaining more fully the true purpose of an Otzar Beis Din, which is a halachically
approved method of distributing Shemita produce, we must first review
the halachos of Shemita. These rules fall under two general
categories:

(1) Laws of the Land

The Torah teaches that every seventh year is Shemita,
and we are prohibited from working the land of Eretz Yisroel. One may not plow,
plant, prune, or harvest one’s grapevines as an owner, or perform most other
agricultural work. Furthermore, one may not allow one’s land to be worked
during Shemita, even by an aino Yehudi.[1] One
may perform activities whose purpose is to prevent loss, such as watering
plants and trees so that they do not die.[2]

Good to Go With Shabbatto!

By: Rabbi Mordechai Frankel

Spring 2022

People look forward to Shabbos as a day to daven in shul and enjoy
the company of other Shomer Shabbos members of the community. Unfortunately,
there are people with mobility issues who are housebound on Shabbos and, for
them, Shabbos is a lonely day. But thanks to newly developed technology by
Movinglife, an Israeli firm, the housebound now are afforded a new opportunity
to rejoin the tzibbur and to enhance their enjoyment of Shabbos. We are
very excited to announce STAR-K certification of the Shabbatto folding scooter,
a new personal mobility device with a Shabbat Mode option.

The road to certification began with Movinglife contacting STAR-K
to discuss their project. After approaching STAR-K to seek certification, the
Movinglife management team met with Rav Moshe Heinemann shlit”a, STAR-K’s
posek and Rabbinic Administrator, at his home. This initial meeting
lasted a good few hours, during which Rav Heinemann explained in detail what he
would permit and what he would forbid for Shabbos use.

Machine Matzos: Timing is Everything!

By: Rabbi Tzvi Rosen

Reviewed March 2024

Meticulous, scrupulous and passionate are terms that describe the fervor, zeal and seriousness displayed by the kosher consumer regarding Pesach kashrus in general, and Pesach matzos in particular. The kosher consumer has become more sophisticated and savvy with each passing year. Kosher consumers are willing to pay top dollar for a quality kosher product. Pesach matzohs are no exception. Machine matzos with fine mehadrin hechsherim are readily available on the supermarket shelf. Are all machine matzos created equal?

Regarding matzah baking and the time parameters for chimutz, leavening, the Shulchan Aruch1states, “One should not leave the dough dormant, not for a moment.” If the dough is constantly being worked the chimutz process is impeded.However, the Shulchan Aruch continues, “If the dough is left dormant for a ‘mil’, the dough […]

The Traveler’s Halachic Guide to Hotels (Including Guidelines for Shabbos and Pesach)

By: Rabbi Zvi Goldberg

Updated February 2024

Yosef chose the hotel he was staying in for its many amenities, not the least of which was the free Continental Breakfast it offered its guests. Surely, when kosher symbols on products are becoming more and more prevalent, he wouldn’t starve! The breakfast menu included cereals, pancakes, waffles, muffins, pre-cut fruits and vegetables, hardboiled eggs, as well as hot coffee and juices. Can Yosef eat anything offered on the Continental Breakfast menu, or should he prepare his own breakfast using the microwave and coffeemaker in his hotel room?

Chana’s brother’s bar mitzvah, held in a hotel during Shabbos, turned out to be a real nightmare! The closet light went on automatically when she opened the closet door; the housekeeper had turned off the light in her room, preventing her from reviewing her Parsha notes; she drank a bottle of water from her room’s ‘refreshment bar’ which unbeknown to her […]

Navigating the Ins and Outs of Renting an Airbnb (Including Guidelines for Shabbos and Pesach)

By: Rabbi Zvi Goldberg

Winter 2024

Who would have imagined, just a few years ago, that you could go on vacation and rent a stranger’s private home? But that is exactly what people now do every day, with the rise of Airbnb and similar short-term rental platforms that list millions of units in over 100,000 cities.[1]

A Torah-observant individual who enters into such an arrangement will encounter numerous halachic challenges when signing up as an Airbnb “guest.” This includes properties listed as “kosher” – even ones in Israel – since an owner usually cannot vouch for every renter who has used the kitchen, nor for each renter’s kashrus standards, which can vary widely. Likewise, one who owns and is the “host” of an Airbnb property will have to address his own set of halachic concerns. Let’s analyze some of the more common ones.
