Keeping Kosher as a Mitzvah
In this lesson: You’ll explore why Jews keep kosher and practice asking about food in a way that is clear, respectful, and easy for someone to answer.
The wedding buffet
You’re at a wedding. You’ve just found a cousin you haven’t seen in years. The two of you walk over to the buffet, and you ask whether the food is kosher.
“Yeah, I think so,” your cousin says. “Someone told me a rabbi blessed it.”
Why do Jews keep kosher?
Jews keep kosher because kashrut is a mitzvah, a commandment from G‑d. In Leviticus 11:44–47, the Torah connects dietary laws with holiness. In practice, keeping kosher shapes ordinary choices, from buying lunch to preparing dinner for guests. Kosher supervision helps people verify how food was made and whether it meets the applicable requirements.Source: Leviticus 11:44–47 · www.chabad.org
The chapter moves from specific details about what people may eat to a call to be holy. That connection puts some of the most ordinary choices we make, including how we prepare lunch or shop for dinner, inside Jewish religious life.
Think about how often you make food decisions in a single week. You buy something on your way to work, order lunch, pick up a snack for a friend, or decide what to serve Friday night. Most of those choices take only a few seconds. Kashrut gives you something to pay attention to in those seconds.
Some of the nicest examples happen before anyone sits down to eat. A host asks a guest which supervision they rely on before placing an order. Someone in the kitchen sets out the right serving utensils so the next person can help without guessing. A friend learns which bakery to stop at so everyone can share dessert. From the outside, these can look like small logistical details. For the people at the table, they can be the reason everyone gets to eat together.
Does a rabbi bless food to make it kosher?
A bracha before eating is a blessing that expresses gratitude to G‑d. A blessing does not change a food’s kosher status. If you’re holding an apple, you might ask which bracha to say. If you’re standing at a catered buffet, you might first ask who supervises the food. Each question has its own answer.Source: www.chabad.org
Here’s a question that sometimes comes up once students hear that explanation: “Then what is the rabbi doing at a kosher food business?”
That’s a good question. The work of kosher supervision is to verify that the food and the operation meet the applicable requirements. That can include checking ingredients, understanding how equipment is used, and overseeing preparation or handling. For certain foods, Jewish participation in preparation is itself part of the halachic requirement. You’ll study one example of that in Who Takes Part in Cooking?Source: www.chabad.org
Who Takes Part in Cooking?
This is where the three questions from Lesson 1 come back. What went into it? How was it made? How will it be served? At home, you may know the answers yourself. At a wedding, the supervision is how you can learn what was verified and who stands behind it.
How do you ask without making it awkward?
You can keep it simple. Start with the detail the other person is most likely to know.
| If someone says… | You can ask… |
|---|---|
| “The caterer does kosher events.” | “Do you know who’s supervising the food for this wedding?” |
| “Some of the food came from a kosher bakery.” | “Do you know which bakery, and which items came from there?” |
| “The organizer has the certificate.” | “Could you send it to me? I’d like to check what it covers.” |
Notice how the questions get more specific as you learn more. You can thank someone for helping and still ask a follow-up. If the person you ask doesn’t know, that’s information too. You can check with the organizer or the certifier instead of asking your cousin to make a judgment for you.
Follow the conversation
Screen 2 — The organizer sends you a document. It shows a certifier’s name and a different branch address from the one you expected. The document says nothing about the off-site wedding. Tap each detail on the fictional certificate.
Text version of this activity
- Issued by (Fictional Kashrus Council): Who issued it: this tells you which certifier stands behind it, so you can decide whether you rely on them and contact them.
- Location (Riverside Catering — Oak Street branch): This is a different branch address from the one you expected. Certification is often tied to a specific location.
- Covers (Food prepared and served on these premises): What it covers: the scope says nothing about off-site events, so it doesn’t yet tell you whether this wedding is included.
Screen 3 — Your cousin says: “Okay, I get it. So you’re trying to figure out what bracha to make?” Write a one-sentence reply before revealing the sample.
Bring it back to your own table
You’re hosting next week. A guest asks about the bread and tells you there’s a particular standard they follow. What can you do today that will make dinner easier for both of you?
