This might come as a surprise to some, 尤其是逾越节期间 (逾越节), 当食品限制引发许多问题时. 荞麦, 尽管它的名字, 不是小麦的一种, 因此不属于 chametz 的范畴. But what exactly is chametz? And how does buckwheat compare to chametz grains in terms of use, 营养, and tradition?
Let’s explore.
What is Chametz?
In Jewish tradition, chametz refers to leavened products made from five specific grains that have come into contact with water and have been allowed to ferment (rise). According to the Talmud (Pesachim 35a), the five grains that can become chametz are:
| Chametz Grains | Notes |
|---|---|
| Wheat | Most common in bread and baked goods |
| Barley | Used in beer and porridge |
| Spelt | An ancient grain, related to wheat |
| Rye | Often in rye bread |
| 燕麦 | Subject to debate; often used in matzah for gluten-free needs |
If any of these grains are mixed with water and left to stand for more than 18 minutes before baking, they are considered chametz and forbidden during Passover.
Why Buckwheat Is Not Chametz
Despite its misleading name, buckwheat is not related to wheat or any grain family botanically. Buckwheat is a pseudocereal, meaning it’s a seed from a flowering plant (Fagopyrum esculentum) that behaves like a grain.
Key points:
| Characteristic | 荞麦 |
|---|---|
| Botanical family | Polygonaceae (not Poaceae) |
| Leavening potential | Cannot become chametz |
| Passover status | Permitted (for Ashkenazim, not consumed; for Sephardim, often allowed)* |
| Gluten content | Naturally gluten-free |
*笔记: Many Ashkenazi Jews treat buckwheat as kitniyot (legume-like foods prohibited by custom, not law, during Passover), 但 Sephardic Jews often allow it.
How Is Buckwheat Commonly Eaten?
Buckwheat is widely consumed around the world in various forms:
Groats (Kasha) – Roasted whole buckwheat, common in Eastern European dishes.
面粉 – Used for gluten-free pancakes, noodles (like Japanese soba), or baked goods.
Noodles – Soba (日本), often made with a mix of wheat and buckwheat flour.
➤ Are any of these chametz?
Only if wheat is mixed in, such as in many soba noodles (check the label). Pure buckwheat products without chametz grains are not chametz.
