The beracha for matzah brei
Question
Answer
Shalom u’vracha.
If he fried it in large pieces, such that each piece contains a kezayit, he recites the blessing “haMotzi.”
For pieces smaller than a kezayit — if he fried them in deep oil, he recites “Mezonot” (as the halacha for cooked matzah).
— If he fried them in a small amount of oil (just enough so that the matzah does not burn), he recites “haMotzi.”
— If he fried them in a medium amount of oil that imparts flavor to the matzah, there is doubt as to which beracha to recite, and it is preferable to eat it within a bread meal. If he does not eat it within a meal, he should recite “Mezonot.”
If he fries pieces smaller than a kezayit in such a way that the matzah becomes submerged in the egg during frying, he recites “Mezonot,” as with cooked matzah.
