A proper kosher Passover matzah must take, from start to finish, no more than 18 minutes. Any longer and the leavening begins. Any longer and it becomes chametz, unfit for the eight-day Jewish spring festival that begins this year at sundown on April 10. Unfit even to be in sight during the holiday.
In many big cities worldwide, it is a tradition for Jewish children to tour a traditional matzah bakery and watch as bakers hand-make the unleavened bread.
But in the Twin Cities, there is no traditional matzah bakery and so, like his father before him, Rabbi Mordechai Grossbaum of the Minneapolis Chabad Lubavitch teaches the tradition to Jewish children here through words, songs and lessons.
The makeshift Model Matzah Bakery was open to the public Sunday at the Sabes Jewish Community Center in St. Louis Park. About 100 people came to learn.
The children (with a little help) took the shafts of wheat and separated the grain from the chaff, making a happy mess on long, paper-covered tables. Each small pile of grain went to the wheat grinders, which turned it into flour.
Noah Altman, 3½, was helped by his mom, Jordana, while dad, Adam, watched.
"We came out today to support the Chabad Lubavitch," Adam Altman said. "And to give my son the experience of baking matzah."
Altman explained that matzah is the "bread of affliction." When the Israelites fled slavery in ancient Egypt and walked into the desert, the sun baked the dough they carried before it had time to rise.
