I made homemade pizza today. Used the same recipe for the dough as I used in the past, the one that came with my bread maker. I made the dough in it, took it out and pressed it into the iron skillet I always use and let it rise. When the pizza was done, though, the crust was hard to eat. Very tough and I don't know what I did wrong. I did notice that the crust didn't rise hardly at all and am wondering if that was why? My yeast wasn't expired or anything.
