Security

By: Rabbi Moshe Heinemann

Published Spring 2015

In these turbulent times, many people have installed alarm systems in their homes which give them a sense of security. There are various types of burglar alarms which may or may not be connected to a central system, and it is clear that the system will work only if all is intact, the component codes are set in the right sequence, and the unit is in working order. It is a good idea to test it every now and then to make sure the system is in proper operating condition. All it takes is one faulty connection to negate the whole system.

Our feeling of security should come from the recognition that we have a protector in heaven, rather than relying entirely on some mechanical device devised by man. The Ribbono Shel Olam watches over our homes if we do His will. The mezuzah attached to our doorpost is our protection. It is a direct link to the “Central System”. Certain letters […]

Surprise Du Jour

By: Rabbi Tzvi Rosen

Published Summer 2015

TYPICAL RESTAURANT SCENE #1: “Ma, I’m going to grab something to eat before supper.” “Fine, but don’t make yourself fleishig. We’re having milchigs tonight.” “No problem. I’ll just get an order of fries from Kosher Burger!”
Was that a fatal supper flaw or not? Possibly, but it is not uncommon for afleishig restaurant to cook their french fries or onion rings in the same fryer that is used for chicken. If that is the case, the fries are 100% fleishig and the little boy is cooked! One would have to wait the required amount of time before eating a dairy meal.[1]

This is not the only pareve pitfall for an unassuming kosher consumer. There are many other factors to be aware of when dining at a fleishig restaurant. Just as a fryer can be used for both meat and pareve products, so can the knives that are used to cut salad vegetables. Also, frying pans used between cutlets and vegetables, or ovens that cook any number of meat and pareve food […]

Three Mentchen Ready for Bentchen

By: Rabbi Dovid Heber

Published Summer 2015

The scene is ever so common in Jewish homes. A delicious meal is served and followed by mayim achronim . Then one of the participants of the mezuman proclaims, “ Rabosai mir vellin bentchen ”[1] (Gentlemen, let us recite Birchas Hamazon ), and everyone present responds.[2]

The basic halachos are well known. If three men who have reached the age of Bar Mitzvah [3]eat bread[4] together, they form a “ mezuman. ”[5] One of them, known as the “ mezamein ” is the leader.[6] If there are ten men, “ Elokeinu ” is added[7] by the mezamein between the words “ Nevoraych ” and “ She’ochalnu ”, and by the rest of the group between “ Baruch ” and “ She’achalnu ”.

Eruv Chatzeiros in a Hotel on Shabbos

By: Rabbi Mordechai Frankel

Kashrus Kurrents Fall 2013

Q: When a person stays in a hotel for Shabbos, does he need to make an eruv chatzeiros to allow him to carry items in the hallways and lobby?

A: In order to answer this question, we need to review some of the basic halachos of eruv chatzeiros.

In the times of Chazal, it was common for private houses to be situated around the perimeter of a rectangular central courtyard, known as a chatzeir. The chatzeir was used by the members of these houses for chores, such as washing clothes and grinding grain. The Torah considers a chatzeir to be a reshus hayachid (a private domain) if it is surrounded on all sides by walls of the houses and one could, therefore, carry in the chatzeir on Shabbos. However, due to the fact that a chatzeir is less private than a house, the Rabonnon forbade […]

Beyond Milk and Meat…

Published Fall 2013

This past spring and summer, applicants from across the U.S., Mexico and Canada took advantage of an array of kashrus education opportunities hosted by STAR-K Kosher Certification in Baltimore, Maryland. In April and June, STAR-K administrators addressed the rabbinic alumni of Yeshiva University’s Rabbi Isaac Elchanan Theological Seminary (YU/RIETS) and Yeshivas Ner Yisroel, respectively, during their Yarchei Kallah. In July, STAR-K held back-to-back Foodservice Kashrus Training and Tenth Annual Kashrus Training Program seminars. Rabbi Dovid Yachnes, rav of the Orlando Torah Center, wrote a letter of appreciation that perhaps best sums up the impact made during all of these educational efforts. Commenting on these efforts, STAR-K President Avrom Pollak said, “STAR-K is always interested in supporting rabbonim and their communities around the country and the world, with accurate kashrus information and halachic resources, to further our mission of promoting kashrus and observance of halacha.”

Dear STAR-K,

Maintaining Proper Standards of Kashrus In Our Yeshivos & Schools

By: Rabbi Dovid Heber

Published Fall 2013

Kashrus has come a long way. Kashrus agencies ensure the highest standards of kashrus in factories and food establishments worldwide, by maintaining a staff of experts in halacha, and in food technology, equipment and ingredients. Consumers have been trained to know which products are acceptable and how to maintain a kosher kitchen l’mehadrin. Kashrus in shuls is usually overseen by the rav of the kehila.

However, one area of kashrus that has received little attention – even throughout the past several decades of unprecedented kashrus growth – is kashrus in our schools. These “heiligeh mekomos”, where tens of thousands of our “tinokos shel bais rabban” spend much of their time during the course of their formative years, deserve the same attention as factories, eating establishments, shuls and our homes.

It is difficult to address the needs of each school as every situation is different. The issues at a yeshiva with a full-service […]

Kashrus Goes Crunch

By: Rabbi Tzvi Rosen

Published Fall 2013

Everyone wants to emulate a winner. The world of food manufacturing and marketing is no exception. Whenever a new product reaches the marketplace, or a new business venture is successfully launched, rest assured that product or venture will be duplicated, cloned, or modified
immediately. One only needs to travel north of Baltimore to Pennsylvania Dutch country to see this in reality. Southern Pennsylvania is home to tens of snack food manufacturers, and is aptly dubbed “the snack food capital of the United States.”

Snack foods have always been an integral part of the American diet and the American way of life. But, snack food modifications do not stand still. As our eating habits, tastes, and health awareness change, so have snack food styles. As production streamlines and technology becomes more innovative, snack food companies continuously modernize to keep up with the times. Of course, one dimension of the snack food industry that always remains constant is kashrus. No matter how […]

Sheva Brachos Guidelines

By: Rabbi Mordechai Frankel

Kashrus Kurrents Spring 2013

Q: Could you give me some guidelines as to when sheva brochos are recited?

A: When a chosson and kallah get married, sheva brochos are recited on three occasions: (i) under the chupah, (ii) at the end of the meal following the chupah, and (iii) at the end of subsequent meals that are made lekovod the chosson and kallah. It is this third category which is commonly known as sheva brochos. If the chosson and kallah have both been previously married, sheva brochos are recited only on the day of the wedding.1 If either the chosson or kallah has not been previously married, sheva brochos are recited on the seven days following the wedding, with the day of the wedding reckoned as the first of those seven days.2 If neither the chosson nor the kallah have previously been living an observant lifestyle (or if one […]

Getting Into the Thick of Things: GELATIN

By: Rabbi Avrohom Mushell

Published Spring 2013

Have you ever had a slice of p’tcha galarita – that spicy, globby stuff Bubby used to cook up? How did she manage to make it so thick?

Better yet, open a can of gefilte fish. Look at the stiff jell that comes as its broth. Why is it that when you cook your own gefilte fish, you do not get that solid jelly from your broth? Did you ever wonder why theirs is so thick and yours is not?

COLLAGEN may be the answer to this thickening question.

Collagen is a fibrous, insoluble protein that makes up a major portion of bone, skin and connective tissue. By cooking animal bones or adding fish bones to the broth of your gefilte fish, you will extract some of the collagen from the bones. This gives you the wobbly jelly in p’tcha or in the gefilte fish that comes in a can.

The most common form in which collagen is marketed is partially hydrolyzed state known commonly as gelatin. […]

Shmitta 5761

By: Rabbi Dovid Stein

For over nineteen hundred years the Jewish people have longed to return to Eretz Yisroel, the land of Israel. It is only in land of Israel that we can realize our full potential as a nation; it is only in the land of Israel that the Torah’s blueprint for life can be completely fulfilled. Over the millennia the most important dimension of this longing was the yearning to once again be able to fulfill the mitzvos hatluyos ba’aretz (agricultural laws), the commandments that can only be observed in the land of Israel. With Hashem’s help many of us in this past generation have realized part of this two thousand year old dream. Yet, this realization has presented us with new challenges.

The Mitzvah of Shatnes

By: Dr. Avrom Pollak

This article is an attempt to provide a review of some of the pertinent details of the mitzvah of shatnes, to educate consumers so that they avoid purchasing garments containing shatnes, and to dispel many of the myths about certain types of clothing and textiles that do or do not contain shatnes. We hope to reduce the all too frequent instances in which the joy one naturally experiences upon purchasing a new garment is diminished when shatnes is discovered.

Mitzvos on the Fringe

By: Rabbi Moshe Heinemann

Just as the Torah carefully directs us in the arena of kosher diet, what we can and cannot eat, how food may and may not be prepared, and what foods are considered required eating, similarly, the Torah provides us with a kosher dress code regarding the clothing we wear, what fabrics or combination thereof may or may not be used, how clothing should or should not be worn, and what styles of clothing are recommended. One of the Torah‘s great “how to” mitzvos is the mitzvah of tzitzis. The Torah instructs us to insert specially wound fringes onto the corners of any four cornered garments where the corners surround the wearer.

Good Fences Make Good Home Owners

by Dr. Tzvi White, reviewed by Rabbi Moshe Heinemann, Star-K Rabbinic Administrator

Home ownership, the American dream. After moving in one hopes it doesn’t turn in to an American nightmare. So many things to take care of; so many things to consider. Utilities, the structure, the appliances – the list is seemingly endless. Dealing with normal home issues is hard enough, just think how many more issues have to be considered in a kosher compliant home. Kosher mezuzas on all entrances. Kosher appliances to make the kosher kitchen user friendly. No trees hanging over the backyard area where the sukkah is to be built. Moreover, does anyone realize that roofs, porches, balconies and landings have to be kosher as well? How do you make a porch kosher compliant? The answer – build a ma’akeh.

When You Need to Knead: A Guide to Hafrashas Challah

By: Rabbi Dovid Heber

Fall 2004 | Updated April 2026

[For a related article about the halachos of hafrashas challah for gluten-free blends, whole wheat flour, sourdough and at challah bakes, click here.]

One of the many ways Klal Yisroel serves the Ribbono Shel Olam is through the performance of mitzvos hateluyos ba’aretz, mitzvos that are dependent on the Land of Israel. Those who live in Israel have many opportunities to fulfill these mitzvos. In chutz la’aretz, the mitzvah of hafrashas challah is one of the only agricultural mitzvos that we are obligated to perform.1

It is well known that this is one of the mitzvos performed preferentially by women. Furthermore, one honors the Shabbos by baking and being mafrish challah on Erev Shabbos.2

The following are halachic guidelines based on the psak of Rabbi Moshe Heinemann shlit”a.3

Pas or Pas Nisht: Reviewing the Laws of Pas Akum

By: Rabbi Tzvi Rosen

Life is made up of a long chain of experiences. Some bitter, some sweet, some mundane, and some exciting. Let me share one with you. About ten years ago I had the good fortune to have an inspiring experience in Morocco, of all places. The purpose of my trip was to inspect various Star-K companies that exported olives and olive oil to the U.S. The inspiration came as a result of spending two days with the remnant of the once thriving ancient Jewish community of Meknes. Meknes was home to many Rabbanim, Geonim, and Tzadikim. The Ohr Hachaim HaKodosh, the great luminary who wrote the famous commentary on Chumash, was born in Meknes. The Jewish cemetery dates back 1200 years. Today barely two hundred families remain. The Rav of the small kehilla is a holy Jew by the name of Rabbi Chaim Kasous, who had served […]

FOOD FIT FOR A KING: Reviewing the Laws of Bishul Akum & Bishul Yisroel

By: Rabbi Moshe Heinemann

It is not uncommon for food manufacturers to call us with a keen interest in kosher certification but who don’t have the slightest idea what it takes to produce a kosher product. What complicates matters is that they would like to have a kashrus tutorial capsulized into a telephone conversation. Obviously, we can’t give a thorough kashrus course over the phone, but we can categorize practical kashrus into three main areas: ingredients, equipment, and process.

The Rise and Fall of Wonder Bread

By: Rabbi Tzvi Rosen

Published Spring 2013

It has been called the staff of life. “Lechem” (bread) makes a quick cameo appearance for posterity, when the Ribbono Shel Olam charts the course of mankind for time immemorial by punishing Adam HaRrishon with the words, “Bezaias apecha tochal lechem”,1 “You will eat bread by the sweat of your brow.” Of course, it is obvious to everyone – both young and old- that lechem means bread!

In the course of his daily routine, a mashgiach deals with dozens-if not hundreds-of food ingredients. In the arcane world of modern food technology, terms like “enzymes”, “substrates”, “emulsifiers”, “stabilizers”, and “surfactants” lend some technical significance. But, in the real world one may ask, “What has an enzyme done for me lately?” This article will address some of the direct applications of enzymes in our diet.

Terumos and Ma’asros

By: Rabbi Moshe Heinemann

Published Spring 2002 | Updated August 2024

Eretz Yisroel has the unique privilege of being the recipient of the Ribono Shel Olam’s brachos throughout the year. Its agricultural industry continues to grow and flourish. Consumer products from Israel that are exported to the American marketplace include Jaffa oranges, grapefruits, pomelos, clementines, carrots, parsley, Carmel and canned tomatoes, peppers, candies, jams, jellies, olives and pickled products. Industrial products used for manufacturing include tomato sauce, tomato paste, orange oil, lemon oil and spices.

Besides for all the ingredients and processing concerns which confront the kosher consumer, additional kashrus requirements apply to foods grown, produced or imported from Israel. A consumer must be sure that terumos and ma’asros have been properly separated before eating, and that the fruits do not come from trees that are orla or neta revai or shemita.

Charting the Course of Orla

By: Rabbi Dovid Stein

Published Summer 2013
When a tourist comes to Israel from the Diaspora one of the things he has to get used to is the mitzvos hatluot b’aretz, the mitzvos that are unique to Israel. After he gets through taking trumah and maaser, tithing, and makes sure he doesn’t come during shmitta (beware next year!) he is suddenly hit with orla. And when he asks how to cope with this unfamiliar problem he is sometimes given a chart with a list of fruits and orla percentages which, if he isn’t totally confused, the charts will certainly finish off the job. “What do all these percentages mean? And why,” he asks, “can’t someone give me a yes or no answer instead of these percentages?” So what do the percentages on these fruit charts mean?

A Halachic Exercise in self control

By: Rabbi Tzvi Rosen

Published Summer 2013

SCENE 1: You are hungry. You desperately need something to hit the spot. Suddenly your friend offers you a delicious chocolate frosted cupcake . . . complete with sprinkles. Your mouth begins to water . . . you are just about to take that first irresistible bite when your inner voice raises the age-old query, “How do you know if it is Kosher?” Your ecstasy is short lived. Your hand pulls back and you put the cupcake down. You exercised self control. You are still hungry but you passed the test.

OTZER BAIS DIN: Proper Distribution of Shmitta Produce

Rav Aharon Tendler, Ner Israel Mechina High School

Our rabbis have taught that if the Jewish nation would observe two Shabbosos, they would be immediately redeemed1. Generally, this is understood to mean that the redemption will come if we observe two consecutive Shabbosos. The question arises as to the significance of two Shabbosos, and many responses have been provided. There is a beautiful answer offered by the former Chief Rabbi of Moscow, Rabbi Fishman, in his introduction to a commentary on the Yerushalmi Mesechta Shevi’is. Rabbi Fishman maintains that the two Shabbosos actually refer to the seventh day of the week when we refrain from all melacha, constructive work, and the seventh year of shmitta, when we withdraw our ownership from the land of Israel and declare all produce ownerless and available for all to take.

The Kashrus of Tea – With No Strings Attached!

By: Rabbi Baruch Beyer

Published Summer 2013
Americans, generally, do not drink as much tea as the rest of 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 and what questions there are vis-à-vis kashrus and halacha. First, a little background is in order.

Kashrus in High Spirits

By: Rabbi Tzvi Rosen

Winter 2005

Jewish life-cycle events, be it a bris, a bar mitzvah, or a wedding, are special occasions that we anticipate eagerly and celebrate with joy. At any simcha, we fill our cups with wine, raise our glasses of schnapps, and with great fervor pronounce a resounding “L’chaim!” in honor of the blessed event. This custom of melding alcohol with simcha has been a Jewish practice from time immemorial. The cup that is raised today, however, bears very little resemblance to that of yesteryear.

It’s a Siman That It’s Kosher: Avoiding Basar Shenis’aleim Min Ha’ayin

August 2013

An interview with HaRav Moshe Heinemann, STAR-K Rabbinic Administrator

The world of kashrus has played, and continues to play, a dominant role in the life of a Jew and the life blood of Judaism. This centrality is evidenced by the significant halachic treatment of kashrus in the Shulchan Aruch, by our poskim, and in contemporary Torah journals, as well as the particular attention paid to the kosher consumer stretching from the aisles of the supermarket to the media portfolios of the marketplace.
