I've been teaching four hour bread classes to raise money for my daughter's school and for the food bank, and it's been amazingly fun. For each class we bake a pizza for lunch (with wine and beer if there are adults) and make a few breads. Usually a sourdough, and a couple of others as they request. I just did a class for four middle-school aged girls where we made two soudoughs, pizza, monkey bread and cinnamon rolls -- they were a fantastic group.
Anyway, tons of fun.
