CHICAGO (WBBM NEWSRADIO) -- A convoy of small buses, dubbed "Mitzvah Vehicles" drove into the Loop on Monday at noon, before spreading out over the city to bring Passover greetings from a school in Skokie.
What they're bringing to people in Chicago is Shmurah Matzah, which is watched to make sure it doesn't come into contact with water. A high standard of kosher.
"They're careful. They keep it dry...And that's what keep it from rising," Rabbi Moscowitz said.
WBBM Newsradio: It would expand a little bit. But yeast is what makes it rise.
"Yeast is the cheating way to make it rise. But without yeast, things still rise," he said.
