Pas Habah B’Kisnin: Pas or Pas Nisht

Pas Habah B’Kisnin: Pas or Pas Nisht

By: Rabbi Tzvi Rosen

Spring 2005 | Updated August 2013

…Sora spent the whole morning shopping and was ready to stop for lunch. She was in luck. The kosher pizza shop was down the block from the mall. Since she was watching her weight she did not want to indulge, so she ordered one slice, salad and a diet soda. As she carried her order to her seat, she was faced with a dilemma: which brocha (blessing) should she make – mezonos or hamotzi?

…It was a beautiful wedding with a magnificent stand up smorgasbord. Naturally, the guests lined the carving tables to indulge in delicious corned beef. The glatt[...] Read More

Kashrus in High Spirits

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.

Candy is Dandy

Candy is Dandy

By: Rabbi Tzvi Rosen

Kashrus Kurrents, Winter 1997

Walking through a candy store leaves one with little doubt that great creative genius has been a long time associate of the candy industry. It is an absolutely amazing act of wizardry to see the multitude of confectionery varieties, shapes, textures, and tastes that can emerge from sugar, chocolate, and corn syrup. Chewy caramels, cotton candy, lollipops, chocolate pralines, nut logs with creamy nougat fillings, the list is endless.

So what could be wrong with candy? Especially if the ingredient panel states only simple, natural ingredients? Not so simple.

At times a product may have nothing that presents a Kashrus problem, but at other times the seemingly identical product can be very problematic.

Let’s take a behind the scenes tour of Kosher candy manufacturing, where we can examine the production processes and procedures of some of the popular delicious confections enabling us to pinpoint the Kashrus […]

Heating & Cooling – Using Ice from an Ice Maker on Shabbos | Using an Electric Hot Water Heater on Yom Tov

Heating & Cooling – Using Ice from an Ice Maker on Shabbos | Using an Electric Hot Water Heater on Yom Tov

By: Rabbi Mordechai Frankel

Kashrus Kurrents Winter 2008

Q: My freezer has an ice making machine, which has an arm that rises as ice is produced and lowers when ice is removed. I generally turn the machine off before Shabbos by lifting the arm until it is fully raised. If I forget to do this, can I remove ice on Shabbos from the ice maker?

A: There are various types of ice maker machines available, and they do not all work in the same way.  However, many of the commonly available models employ the following mechanism.  The ice making process begins when the ice maker signals the water valve to open, and a specified amount of […]

Q: May one enter a non‐kosher restaurant to get a drink of water, use the restroom or attend a business luncheon?  If a person does enter such an establishment, may he eat kosher items such as whole fruit?  May one buy a cup of coffee at a non‐kosher facility, such as a highway rest stop or Starbucks?

When Non-Mevushal Wine Becomes Stam Yeinom | Shipping Packages for Shabbos Delivery

Kashrus Kurrents Fall 2009

Q:       I had a bottle of wine stored in the shelving unit on the door of my refrigerator.  I was in the kitchen, and I saw my non-Jewish hired help open the refrigerator.   She knows that she is not allowed to touch my wine, but did not pay attention to the fact that opening the refrigerator moves the wine on the door.  Can I still drink the wine?

Using a Warming Tray on Shabbos

Using a Warming Tray on Shabbos

By: Rabbi Mordechai Frankel

Kashrus Kurrents Winter 2009

Q:       I would like to buy a warming tray that has been manufactured for the Shomer Shabbos community. It is a glass covered warming tray and has a variable temperature dial with a removable knob. It can be set at a minimum temperature of 110 0F and a maximum temperature of 230 0F. It has a sticker on it stating that it is intended solely for the reheating of cooked foods and is not intended to be used for cooking. How may this tray be used on Shabbos?

A:  In order to answer this question, one must have an understanding of the Rabbinic prohibitions of shehiyah and chazarah.  The parameters of these two prohibitions differ for Ashkenazim and Sefardim.  This response will explain the halachah as it applies to Ashkenazim.

Shehiyah:  Shehiyah is the act of placing food on an open flame before the onset of Shabbos […]

Eating in a Canvas Sukkah that Sways in the Wind

Eating in a Canvas Sukkah that Sways in the Wind

By: Rabbi Mordechai Frankel

Kashrus Kurrents Fall 2010

Q: I have been invited to eat out on Sukkos.  The sukkah has canvas walls which shake in the wind.  Is this a problem?

A: The Mishna1 states that a person can use the trunks of trees as a sukkah wall. This Mishna is referring to a scenario where the tree trunks are very close to one another, or the space between them has been filled with some other material, and the overhang of the tree branches will not invalidate the schach. The Gemara2 states that this is true only if the tree trunks do not sway.  If the tree trunks are supple and sway in a normal wind, the sukkah wall is not valid. The Shulchan Aruch3 codifies this halacha, and adds that if the tree trunks are supple one can tie them to each other in such […]

Using a CPAP Machine on Shabbos

Using a CPAP Machine on Shabbos

By: Rabbi Mordechai Frankel

Kashrus Kurrents Winter 2010

Q: My doctor has told me that I have sleep apnea, and advised me to use a sleep apnea machine.  Can this device be used on Shabbos?

A: Sleep apnea is a disorder characterized by abnormal pauses in breathing or instances of abnormally low breathing during sleep.  Obstructive sleep apnea, the most common form of the disorder, is caused by the relaxation of the walls of soft tissue in the airway of the throat during sleep.  Common symptoms include loud snoring, restless sleep, and daytime sleepiness.  Sleep-disordered breathing is associated with an increased risk of cardiovascular disease, stroke, high blood pressure,arrhythmias, diabetes, and sleep deprived driving accidents.1  Recent studies have shown that sleep apnea affects about 16% of men and 5% of women between 30 and 65 years of age.[...] Read More

Getting a Handle On Your Faucet

Getting a Handle On Your Faucet

By: Rabbi Zvi Goldberg

Winter 2012

Torah-observant Jews know that turning on the hot water faucet during Shabbos causes cold water to be heated, which transgresses the melacha of bishul, cooking. What many don’t know is that even turning on what you think is cold water can be a problem – if it’s a one-handled faucet.

Let’s first analyze why using hot water causes cold water to be heated.  In a typical home setting, cold water arrives from the city supply under pressure.  Turning on the hot water faucet allows this cold water into the hot water tank which, in turn, forces out the hot water already in the tank.  Since the water in the tank is typically more than 120oF (the minimum temperature for bishul on Shabbos), the incoming cold water is immediately heated by the hot water that is already in the tank. 1

In a one-handled faucet, both hot and […]

Published Winter 2012
Updated Winter 2019

STAR-K has researched breakfast cereals for the past 30 years and has published Brachos lists and halachic guidelines for these products based on the psak of Rabbi Moshe Heinemann, shlita, STAR-K Rabbinic Administrator. It is with great pride that STAR-K has begun certification of the following three cereals distributed by Nestle in Israel: Cheerios, Fitness, and Crunch Cereals. The hashgacha is coordinated by our newly expanded Israel office. The products bear a STAR-K symbol and are pareve, bishul Yisroel, and yoshon. The brocha rishona on all three cereals is mezonos and the brocha achrona is al hamichya.

Which Materials May Be Kashered (and Which May Not)

Which Materials May Be Kashered (and Which May Not)

By: Rabbi Mordechai Frankel

Kashrus Kurrents Summer 2012

Q: I have a number of utensils which need kashering through hagalah (immersion in boiling water). Which materials may and may not be kashered?

A:   A fleishig utensil which comes into contact with hot milchig food or a milchig utensil which comes into contact with hot fleishig food needs to be kashered before further use.  There are a number of methods for kashering, dependent upon the manner of contact between the utensil and the food.  Perhaps the most common form of kashering is hagalah, in which the utensil is immersed in boiling water.

Metal
The Torah tells us that a vessel may be kashered if it is made from one of six metals:  gold, silver, copper, iron, tin or lead.1  There are other metals and alloys which were not in common use at the time of Matan […]

GO TO LIQUOR LIST

Unquestionably, the latest operative terms in the burgeoning liquor industry are ‘transparency’ and ‘innovation’. Never before has there been more consumer enlightenment, courtesy of the information highway known as the Internet.  Moreover, new venues have been introduced to tweak standard products or present new ones, so that distilleries can gain a greater share of the market.  What previously was assumed to be a glatt kosher choice in the liquor cabinet has now become not so glatt.

Tearing Kriah at the Kosel

Tearing Kriah at the Kosel

By: Rabbi Mordechai Frankel

Kashrus Kurrents Winter 2013

Q: I am going to Israel and will be visiting the kosel (Western Wall). I know that it is customary to tear kriah upon seeing the kosel, but what exactly is the procedure?

A:  The Shulchan Aruch paskens that when a person sees the cities of Judea he should say,
ערי קדשך היו מדבר and tear kriah.1  However, it is not customary to do so, possibly because we do not know exactly where the ancient cities of Judea are located.2  The Shulchan Aruch continues that when a person sees the Old City of Yerushalayim he should say, ציון היתה מדבר שממה , and then tear kriah again.3  Rav Shlomo Zalman Auerbach zt”l writes that even nowadays, one should tear kriah upon seeing the Old City.4  However, Rav Moshe Feinstein […]

Sabbath Mode and Sabbath Compliant Appliances

Sabbath Mode and Sabbath Compliant Appliances

Updated January 2023

Appliance manufacturers, with the aid of modern technology, have designed kitchen appliances to be safer and more efficient while incorporating various features to enhance operation. However, the integration of this technology may pose a challenge to their proper use on Shabbos and Yom Tov.

THE INTRODUCTION OF SABBATH MODE

In 1997, a historic technological project was launched between a major appliance manufacturer and a kosher certification agency. Whirlpool Corporation (manufacturer of KitchenAid) approached STAR-K to help modify their ovens for use on Shabbos and Yom Tov. Prior to that time, many of their appliances did not conform to halachic guidelines.

Following some adjustments, a successful mode was developed. Whirlpool called this “Sabbath Mode” and was awarded a patent in 1998 for this concept.

STAR-K kosher certification on appliances falls into one of two categories:

1. Sabbath Mode Appliances – these are models that have unique software/hardware specifically […]

Bracha On a Newly Flowering Tree: Birchas Ha’ilanos Guidelines

Bracha On a Newly Flowering Tree: Birchas Ha’ilanos Guidelines

By: Rabbi Mordechai Frankel

Spring 2009

Q: There is a bracha which is recited once a year upon seeing a newly flowering tree. I have a number of questions regarding Birchas Ha’ilonos:

When is the optimal time to say this bracha?  Does the bracha have to be said during the month of Nisan? 

What rules apply concerning the location of the person when saying the bracha?  How far away can you be from the tree when saying the bracha?  Can you be inside a house or other structure?  Can you be in a car?  Is it necessary to be at a site where there is more than one tree?

What limitations are there regarding the type of tree over which this bracha may be recited?  Does the tree need to be fruit bearing?  How old should the tree be?  Can the tree be orlah (less than three […]
