Kosher Restaurants: What a Hechsher Tells You

Kosher restaurants are defined by supervision, not by a word on the menu. A kitchen that says kosher is making a claim, and a certificate from a certifying organization or rabbi is the proof. Learning to read that certificate, and what the labels meat, dairy and pareve mean, makes it easier to eat well, whether you keep kosher or are cooking for someone who does.

What is a hechsher?

A hechsher is a kosher symbol. As one educational Jewish site puts it, each symbol comes from a different organization or rabbi. It marks a product, or a kitchen, as meeting Jewish dietary law. Well-known organizations include the Orthodox Union, whose circled U is widely seen, the Chicago Rabbinical Council and Kosher Supervision of America, and there are many more.

Two points are worth remembering. A company's products are not all kosher because one item is, so each label counts. And communities differ on which certifiers they accept, partly because of different views on supervision and standards. If you are hosting, ask your guest which certifications they trust. If you are visiting, ask a restaurant who supervises it.

What do meat, dairy and pareve mean?

Kosher law keeps meat and dairy apart, so food is sorted into categories. Meat, called fleishig, covers meat and anything made with meat or on meat equipment. Dairy, called milchig, covers dairy ingredients and food made on dairy equipment. Pareve, sometimes parve, is neither: no meat or dairy ingredients and not made on meat or dairy equipment, so it can be eaten with either.

The Orthodox Union's markings show the idea on packaged food. A plain OU means kosher and pareve, though not necessarily kosher for Passover. OU-D marks dairy, OU-DE marks food made on dairy equipment, OU-M or OU-Glatt marks meat, OU-F marks fish, and OU-P marks kosher for Passover and pareve. Fish is a separate case: it should not be eaten with meat but can be eaten with dairy.

How does a kosher restaurant work?

Most kosher restaurants choose a lane: a meat kitchen or a dairy kitchen, so that the two never meet. A meat restaurant will not serve cheese or cream, and a dairy restaurant will not serve meat. Fish and vegetable restaurants sit comfortably as pareve or dairy. That is why a menu in a kosher place may seem to lack a dish you expect: there is no cream sauce on a steak, no butter on the vegetables at a meat kitchen.

Supervision means someone qualified watches the kitchen, the ingredients and the practices. A certificate in the window should name the supervising organization and, ideally, the date or period it covers. Opening hours can differ around Friday evening and Saturday, and around holidays, so confirm before you travel.

What should you ask about kosher food near me?

Start with the certificate and the category. Useful questions:

• Who supervises the kitchen, and may I see the certificate?
• Is this a meat or a dairy restaurant?
• Are the ingredients and the supplier also supervised?
• What are your hours on Fridays, Saturdays and holidays?
• For Passover, is the kitchen certified for the holiday as well?

Be careful with similar words. Kosher-style names a style of food, such as deli sandwiches and pickles, and does not mean a kitchen is supervised. Kosher-friendly is a statement by the place itself. If the supervision matters to you, ask.

What does the Kosher tag mean?

Raters on Mosey can attach the stored tag Kosher to a rating, and the Find sheet lets a diner narrow a search to it. The tag is a single diner's note after a single visit. It does not say who supervises the kitchen, and it never tells you whether a place meets your own community's standard. Treat it as a lead, then confirm.

When you rate, record what you saw: the certificate, the organization named, whether the place was meat or dairy and the hours kept. Honest detail such as "dairy restaurant, certificate on the wall, closed early on Friday" lets the next person decide quickly.

How can ratings and lists help a kosher-keeping household?

Rate each dish so others learn which ones the kitchen does best, and tag the friends who ate with you so they can add their own rating of the same meal. Keep a list for places you would send a guest, with a note about whether each is meat or dairy, who supervises it and when it is open. Share the list with family and follow friends who keep the same standard to see their ratings and saves. The lists page shows how to share one.

If you are cooking for or dining with someone who keeps kosher, a list like that spares both of you an awkward moment at the door.

Why does a careful rating help neighborhood kitchens?

Mosey is free for a place to list, has no hidden fees and offers affordable tools, so a small supervised kitchen keeps more of its earnings for the cost of supervision and good ingredients. A clear note from a regular helps the next diner trust a choice. For related reading, see how to find good food in a new city, how to order at a deli and the full set of US food guides.

Other needs come up at the same table, so see restaurants for kids with food allergies and dog friendly restaurants.

After a meal that suited your household, rate the dish in the Mosey app, add the Kosher tag with a line on the supervision and save the place to a list for family.
