Before we are off the subject of matzah, I want to interject this story:
A blind gentile man is attending his first Passover seder. He misses the explanation when a plate of matzah is passed to him. So he takes a sheet of the stuff and tries to figure out what it is by running his fingers over the surface. After a few seconds, he puts it down, shakes his head, and says: "Who wrote this garbage?"
