Matzah brei (Yiddish: מצה ברײַ; Hebrew: מצה בריי, matzah brei, or מצה מטוגנת, matzah metugenet, literally, "fried matzah"), sometimes spelled matzah brie or matzo brei, is a dish of AshkenaziJewish origin made from matzo fried with eggs.
There are many recipes for this dish. Typically the dry matzo is broken into pieces, briefly softened in water or milk, mixed with eggs, and fried. It may be formed into a cake, like a frittata, or broken up and cooked like scrambled eggs. It can be savory or sweet. It may be combined, omelette-style, with other foods. It may also be topped with sauces such as apple sauce, salsa or preserves. Some eat it with sugar, syrup, or jelly. (Note that, in accordance with Jewish dietary laws, if matzah brei is prepared with any dairy product [e.g. butter] it should not be eaten with meat, nor should it contain or be eaten with dairy if cooked in schmaltz.)
Matzah brei is commonly eaten as a breakfast food during Passover, when only unleavened bread is permitted. However, some Jews do not eat matzah brei during Passover because they do not eat gebrochts, matzo that has come into contact with water.
