If one had to choose a single word to describe an olive, it would be ‘versatile’. Olive oil was used daily to light the Menorah in the Bais Hamikdosh. Our first introduction to olive oil was the Shemen Hamishcha, an infused olive oil with a unique blend of spices used to anoint melachim, kohanim and klei haMikdash. Moreover, the yonah (dove) brought back an olive branch to Noach in the ark, and our baseline halachic measurement for eating something significant is a “k’zayis”, the size of an olive.1 The Gemara in Brochos tells us that if one sees an olive in a dream, it is a sign of peace; if one sees an olive branch, it is a sign of Torah scholarship.
There is an opinion in the Midrash that the fruit of the Eitz Hadaas, Tree of Knowledge, was from an olive tree. Additionally, Asher (one of Yaakov Avinu’s […]

Myth #1: Every oven that has a Sabbath mode is certified by STAR-K.
Fact: An oven that has a Sabbath mode may or may not be certified by STAR-K. In fact, the same company may manufacture some ovens which have a STAR-K certified Sabbath mode and other ovens with a Sabbath mode which do not have any certification at all. One can verify an oven is STAR-K certified by consulting the oven’s manual, calling us (410-484-4110), or looking at the list on STAR-K’s website (www.star-k.org/appliances).
Reason: STAR-K does not own the copyright to the term “Sabbath mode” and cannot prevent a company from using those words.

Myth #2: A person who does not intend to raise or lower the oven temperature may use any oven on Shabbos and Yom Tov, and there is no reason to use an oven which has a STAR-K Sabbath mode.
Fact: When using an oven on […]

Before one is permitted to indulge in kosher Jewish delicacies such as chopped liver, liver steaks and onions, or sauteed chicken livers, raw liver must undergo various processes before the liver is deemed fit for kosher use. First, as with all kosher meat, the liver must come from a kosher species of animal or fowl that has been schechted, slaughtered, in the proper manner prescribed by the Torah. If it is an animal liver, all the fat must be meticulously removed. Furthermore, the Torah forbids eating the blood of an animal or bird. Therefore, it is necessary to extract the blood from the kosher slaughtered meat or liver.
How is the blood removed? With meat, this process is commonly known as kashering and is accomplished by soaking the meat in water, salting it, and then rewashing it. With liver, this method of extraction is insufficient. Since liver contains such a large concentration of […]

Q: When is the brocha of Hatov Vehameitiv recited over wine?

A: Before drinking a cup of wine, one recites the brocha of Borei Pri Hagofen. Under certain circumstances, if a different wine is subsequently drunk one recites an additional blessing – the brocha of Hatov Vehameitiv.1 The brocha gives thanks to Hashem for blessing the person with a richness of wine. The Hebrew text of the brocha is

   2ברוך אתה ה’ אלקינו מלך העולם הטוב והמטיב

This brocha is recited only if a number of conditions are met:

If the second wine is of lesser quality than the first wine, Hatov Vehameitiv is not recited.3 There is one exception to this rule. If the first wine is red and the second one is white (but not the other way around), Hatov Vehameitiv is recited even if the second wine is known to be of slightly inferior quality. This is because Chazal consider […]

Glass is one of nature’s most versatile products created from some of nature’s most prevalent raw materials: sand, soda and lime. In the food industry, glass applications are extremely diverse. Glass can be made into delicate drinking glasses, as well as tough heat resistant ceramic cooktops tops withstanding temperatures over 1000°F.
How is glass made? Basically, the raw ingredients are heated and melted in a large furnace. The molten glass is shaped, blown, or pressed into its desired shape. The finished product is then annealed in an annealing oven and tempered to give the newly formed glass strength and durability.
Although glass can be made to be stronger and less porous than steel, the halachic status of glass remains enigmatic. On the one hand, Chazal recognized the fact that glass is tough, resistant and non-porous. On the other hand, glass raw materials are the same as earthenware which is very […]

Gas Ranges

We have been advised that the following STAR-K certified Samsung gas ranges have a Sabbath Mode that does not work properly:


If you own one of these models, click here to contact Samsung for a fix.

Until you get the fix  you need to install an oven “ShabboSwitch”. This device is available at your local bookstore or online. Any method of keeping the plunger switch on the frame of the oven depressed will work.  If using tape, make sure it can withstand the heat of the oven. (Duct tape may not work.)

Please note that you still need to put your oven into Sabbath Mode before Shabbos or YomTov, even if you have installed a “ShabboSwitch”.

Electric Ranges

The Sabbath mode in all STAR-K certified Samsung electric ranges is fully functional and meets all our halachic requirements.

The following contains halachic guidance concerning some of the common issues that arise when conducting a Pesach Seder.  In particular, it discusses preparation for the Seder, the four cups of wine, and the obligation to eat matzah, marror, korech and Afikoman.  This is by no means comprehensive.  For a more comprehensive guide, see HaSeder HaAruch by Rabbi Moshe Yaakov Weingarten (three volumes, 1431 pages).

As the Yom Tov of Pesach nears, and the diligent balabusta begins to tackle the challenge of preparing the kitchen for Pesach, undoubtedly the light at the end of the tunnel is beginning to shine. Although moving into a separate Pesach home sounds very inviting, such luxuries are often not affordable and definitely not in the Pesach spirit. Among the basic mitzvos of the chag is the mitzvah of “Tashbisu Se’or Mibateichem”, ridding one’s home and possessions of chometz. However, if we are to use kitchen equipment, utensils, or articles that can be found in our kitchen year-round, it may be insufficient to just clean them thoroughly. One is forbidden to use these items unless they have been especially prepared for Pesach. This preparation process is known as kashering.
The Torah instructs us that the proper kashering method used to rid a vessel of chometz is dependent upon the original […]

While the act of shechitah itself is an exquisitely humane form of animal slaughter, the manner in which an animal is handled prior to reaching the shochet should also conform with the Torah’s sensitivity for tza’ar ba’alei chaim (the prohibition against causing unnecessary pain and harm to creatures). Our mission to certify meat products of the highest quality was recently enhanced when two prominent members of our meat team, Rabbi Zvi Holland and Rabbi Tzvi Shaul Goldberg, traveled to Iowa in order to take part in an accredited certification program through PAACO (Professional Animal Auditor Certification Organization). Instructors included world renowned experts in the field of animal welfare such as Dr. Temple Grandin, professor of animal science at Colorado State University and consultant to the livestock industry. She is considered a leading authority on animal welfare.

It is written in our Torah, “Ubosor basodeh treifa lo socheilu” (Shmos 22:30), it is forbidden to eat treif meat.  While the expression “treif” (non-kosher) has become the universal connotation for food that is not kosher, in truth, the word treif specifically refers to an animal whose flesh was torn or ripped.  Technically speaking, if a kosher species of animal or fowl was attacked by a predator, the meat of the victim may be deemed treif.  However, the meat of an animal improperly kosher slaughtered is not treifah, it is called a neveila.  Technically, meat of a non-kosher animal species is the meat of a temeiah.  Yet, the term “treif” has found its way through the portals of the slaughterhouse, as well as the aisles of the non-kosher meat section of the supermarkets.  No matter what the name, all of these categories of meat are forbidden to be […]

Keeping kosher does not preclude being a locavore,[1] but it definitely presents substantial challenges, particularly for omnivores. Barely a handful of communities in the world today still host facilities where kosher meat is processed from slaughter to salting, and sold from steak to salami, all within close proximity to a kosher consumer base. Like most items in the modern marketplace, it’s much more common to find beef and poultry products traveling vast distances from slaughterhouse to processor, and from distributor to retailer, before reaching the dinner table.

The Old Way
This very untraditional configuration has uprooted the once prominent communal fixtures of shochet and bodek (one who checks for abnormalities that render meat treifah). It’s also a complete departure from an extreme version of locavorism that was practiced in many pre-war European kehilos, which legislated bans on ‘sh’chutay chutz’, not allowing meat slaughtered in a different city to be […]

Besides pharmaceutical companies, Rabbi Gershon Bess also contacts many cosmetic companies and bases the following chometz-free list on his research.
L’halachah, all non-food items not fit for canine consumption (nifsal mayachilas kelev i.e., something that one would not feed his dog) may be used on Pesach. This includes all cosmetics, soaps, ointments, and creams.1 Nonetheless, people have acted stringently with regard to these items.

Below are several reasons why people are strict:

Many products, including shaving lotion and perfume, contain denatured alcohol which can be restored to regular alcohol. According to most opinions, one should not use such products on Pesach. The list notes products which do not use chometz-based alcohols.
The Biur Halachah (326:10 B’shaar) writes in the name of the Gra that one should be strict and not use non-kosher soap all year (sicha kishtiya). Although we are not accustomed to this stringency, many individuals have adopted this chumra during […]

It has been called nature’s candy and is a sweet source of nutrition whose popularity is on the rise.  Commensurate with its growing popularity is its demand.  In today’s global economy, the dried fruit trade literally spans the entire globe – apples from China, prunes from Bulgaria, figs from the Middle East, dates from Tunisia, raisins from South America, and of course apples, peaches, plums, raisins, figs, and dates from the good old U.S.A.  Naturally, this growth presents a whole new set of challenges to kashrus agencies.  How do they send a mashgiach to supervise date productions in Pakistan, raisin productions in Iran, or plum productions in Bulgaria?  Let’s learn about this popular healthy snack alternative.


The Process

Fruit is dried through a process known as dehydrating, which removes enough moisture from the fruit to retard the growth of bacteria and mold while retaining the great taste and nutrients of […]

Stainless steel, plastic or porcelain dishwashers which have plastic pumps, parts and rubber hoses cannot be kashered for Pesach or the rest of the year.

Porcelain Enamel, Corian, Plastic/Formica, Silestone
CANNOT be kashered (for Pesach). Clean and cover for cold food. Cardboard or thick pad for hot food and utensils.

Granite, Marble, or Stainless Steel
Can be kashered by doing eruy roschim (purging through a hot water pour). Make sure that the material is a PURE granite, limestone, etc. Sometimes they are really “composites” which have plastic in them and therefore CANNOT be kashered.

On Friday, 3 Sivan, 5768, Rav Heinemann, Shlita discussed the recent Kol Koreh regarding raising or lowering temperatures on Yom Tov on ovens equipped with the Sabbath Mode feature.


Electric – Kashering a Glass, Corning, Halogen, or Ceran electric smoothtop range for Pesach use is a bit complex. To kasher the burner area, turn on the elements until they glow. The burner area is now considered kosher for Pesach. However, the remaining area that does not get hot is not kashered. The manufacturers do not suggest covering this area as one would a porcelain top, as it may cause the glass to break. Real kosherization can be accomplished by holding a blow torch over the glass until it is hot enough to singe a piece of newspaper on contact with the glass. However, this too may cause the glass to shatter and is not recommended. As the area between the burners cannot practically be kashered, it would be wise to have a trivet on the open glass area to move pots onto. In addition, it would be wise to […]

Q:   When I say  Al Hamichya and make a mistake, I don’t know what to do.  Could you give me some guidelines?

A:    There are three places in the  brocha me’ein shalosh (colloquially known as  Al Hamichya) where the text changes, depending on what was eaten:

(1)    The  brocha starts with the words “ Boruch atah Hashem Elokeinu melech ha’olamal …”, followed by either “ hagefen  ve’al pri hagefen” if a person drank wine, “ ha’eitz  ve’al pri ha’eitz” if he ate fruit from the  shivas  haminim, “ hamichyeh  ve’al hakalkalah” if he ate food made from any of the five types of grain (wheat, barley, oats, rye, spelt), or a combination of these phrases if he ate or drank a combination of items.1

(2)    Further on in the  brocha , one says “…  ve’nodeh  lecha al ha’aretz ve’al …”, followed by either “ pri  hagofen”, “ ha’peyros”, “ hamichya”, or a combination of these phrases.

(3)    The  brocha concludes with the words “…  Boruch atah Hashem al …”, followed once again by either “ hagefen  ve’al pri hagefen”, “ ha’eitz  ve’al pri ha’eitz”, “ hamichya  ve’al hakalkalah”, […]

Hashem , in his ultimate kindness, has provided man with the keys to unlock some of nature’s most amazing secrets.  For centuries, a great secret has been revealed to man – the bubbling elixir known as beer.

Beer’s ingredients – water, barley, yeast and hops – bear no resemblance to the finished product.  These natural ingredients undergo a series of simple yet fascinating processes to convert them into one of the world’s most popular beverages.  It is not coincidental that alcoholic beverages have been given the distinctive appellation “spirits”, alluding to the fact that these beverages seem to magically emerge from these natural ingredients as if they have been assisted by spirits.  The four steps of beer making are malting, roasting, brewing and fermenting.

THE PROCESS :  The first step of beer making combined barley and water in a process […]

Q:        I would like to send my young children to a backyard camp during the summer.  The camp is offering an ‘early-bird special’ if I register my children now.  If I wait until the summer to register, they will charge more.  Is there any ribbis issue with registering now and receiving the discount?

A:         Ribbis involves lending money to another Jew and charging interest.  Doing so may violate a Torah prohibition or a rabbinic prohibition, depending upon the situation.  If it is necessary to charge interest, the two parties may sign a document known as a “heter iska”, which converts the loan into a business investment, thereby avoiding the prohibition of ribbis.1  People are often unaware that a number of common transactions may violate the prohibition of ribbis.  Here are a couple of examples:

Q: I have heard that someone who bakes loaves of bread with the intention of giving them to other people does not separate challah with a brocha. Can you explain the parameters of this halacha?

A: One is obligated to perform the mitzvah of separating challah when kneading dough which will be baked into bread. The amount of flour one must knead in order to be obligated in this mitzvah is an asiris ha’aifa, which is equivalent to the volume of 43⅕ beitzah.1 The exact volume of a beitzah is a matter of dispute. L’halacha, one should separate challah without a brocha when kneading 2.6 lbs. of flour, which on average is equivalent to 8⅔ cups of flour. According to Rav Chaim Noeh, one can separate challah with a brocha when kneading 3.675 lbs. or more of flour (on average, 12¼ cups). Many follow the opinion of the Chazon Ish, and […]

One of the highlights of the week is the Shabbos seuda. The divrei Torah, zemiros, Shabbos delicacies, family and guests allow us to come closer to the Ribbono Shel Olam and recharge our ruchniyos and gashmiyos (spiritual and physical) batteries. Although a delicious bowl of chicken soup on Friday night and hot cholent during the daytime seuda enhance the Shabbos meals, one does not fulfill his obligation of “seudas Shabbos” with either of these items.
