I have been meaning to start a sourdough starter for a week or so now. Determined to do it tomorrow, I set out to find some kid friendly bread making sites. Little Girl knows that yeast makes the dough go, "Poof!" but that's about all. I found this site . I haven't read all the way through it, but it has some good information and a couple of fun experiments that seem pretty simple. Look up there! My first link!! I hope it works.
