היסטוריה ומקורות
Matzah brei (Yiddish brei, "mash, mixture") is a simple Ashkenazi dish from the period when matzah began to be produced industrially and was available in large quantities; it became especially widespread in America.1
The dispute over gebrokts (soaking matzah) stems from the concern that unbaked flour in the matzah could leaven on contact with water; the custom is widespread mainly in Hasidic communities.

There are two main "camps": sweet matzah brei with cinnamon, sugar or maple syrup, and savory with onion, pepper and sometimes smoked salmon. Depending on the texture, it is made whole like an omelet or as a crumbled scramble.
