01 — The Equation

This is the whole thing.

Chametz is not complicated. Torah gives us a simple formula.

Wheat sheaves and flour in a clay bowl
Grain + Water

Wheat, barley, spelt. The raw ingredient meets water.

Water being poured into a bowl of flour
+ Time to Rise

Left alone, the dough ferments. It rises on its own.

Risen dough overflowing from a clay bowl
= Chametz

It rose. It's leavened. This is what we clean out.

The Result
Chametz.

If grain met water and had time to leaven — it's chametz. This is what we clean out.

That's the whole equation. If it rose, clean it out.

02 — Two Hebrew Words

The starter and the product.

Torah uses two different words. They both get cleaned out, but for different reasons.

שְׂאוֹר
Se'or

The Starter

Se'or is starter dough — flour and water left out until natural yeast causes it to ferment and bubble. Think of it as the "mother" that makes other dough rise. This is specifically what Torah tells us to clean out of our homes.

The Product

Chametz is anything made from grain that came in contact with water and was allowed to rise. Bread, cake, cookies, donuts. If it rose, it's chametz. The word is used broadly in Torah.

04 — Common Questions

The stuff everyone asks.

These are the gray areas. Short answers, no drama.

No. Commercial yeast is a fungus — it's not a grain product. A jar of yeast sitting in your pantry is fine. Sourdough starter, however, IS se'or — that's literally what the word means: flour and water that has been left to ferment. The issue isn't yeast itself. It's grain that has been allowed to leaven.
Beer is made from grain that has been fermented — so technically yes, it falls under chametz. In the Ancient Near East, beer was actually made from bread (bappir). Wine, on the other hand, comes from grapes and has nothing to do with grain. Wine is fine.
Pasta is grain and water, but it never rises — it goes straight from mixing to cooking. The chametz equation requires time to leaven, and pasta doesn't get that. Use your own conviction here, but we don't consider it chametz.
The list of five specific grains (wheat, barley, spelt, rye, oats) comes from the Mishnah (Pesachim 2:5), not from Torah directly. The 18-minute rule comes from the Talmud (Pesachim 46a). Both are rabbinic traditions developed centuries after Sinai. This guide follows the commandments as written in Torah. We honor these traditions and the faithful communities who observe them.
Regular wine is made from grapes — it has nothing to do with grain, so it's not chametz. "Kosher for Passover" is an Orthodox certification that also avoids certain additives and processing agents. If you're following Torah as written, wine and grape juice are fine.
You're practicing something ancient and beautiful. This isn't about impressing God or checking boxes — it's about participating in something He invited us into. Clean out the obvious stuff. Eat matzah for the week. Be present. You'll learn more each year, and that's the whole point.
A Note on Tradition

This guide follows the commandments as written in Torah. Many faithful communities observe additional customs passed down through centuries of dedicated study and practice. We honor that dedication and encourage everyone to study and follow as they are convicted.

"Get rid of the old leaven, so that you may be a new unleavened batch — as you really are. For Messiah, our Passover, has been sacrificed."
