If you’re curious, the stuff Jewish folks aren’t allowed to eat during Passover is called Chametz. It includes more than just leavened bread.
That is interesting.
I guess before I thought it was more like it was traditional to eat certain things, not that you couldn’t eat other things.
There are definitely things that are traditional to eat. Lamb is often a part of it (we have to have a lamb shank as part of the ritual involved, but eating lamb itself isn’t required). Charoset and horshradish are usually incorporated.
Matzoh is required for part of the dinner. But you can use matzoh to make all kinds of things, like matzoh ball soup, which we have every year.
There’s a lot that goes into it. I’m not Jewish, but I live with a Jewish family and have come to the Seder dinner every year for the last decade or so.
Oh! And wine is part of it. You’re basically required to drink lots of it. Unless you’re a kid, or you can’t drink alcohol for whatever reason (like me, I’m an ex-alcoholic, so I share sparkling grape juice with the kids).
