Aron Streit, Inc. (sold under the name Streit's) is a kosher food company founded in Manhattan, New York City, best known for its matzo. It is the only family-owned and operated matzo company in the United States, and distributes matzo in select international markets.[1] Streit's and its major competitor, New Jersey–based Manischewitz, together hold about 40 percent of the US matzo market.[2]
The factory follows strict kosher laws. Only shomer Shabbat (Sabbath-observing) Jews are allowed to touch the dough. However, once the dough is baked, people of any religion and non-shomer Shabbat Jews are allowed to touch the matzo. The entire process of making the matzo is under Rabbinic supervision. During Passover, Jews are not allowed to eat leavened bread, so the dough must be baked within 18 minutes before it has had time to rise. If the dough sits for longer than this, it is considered chametz – no longer kosher for Passover – and must be discarded.[3]
