I have NO idea what I did. I was doubling a simple bread dough recipe http://www.kingarthurflour.com/recipe... --have done it before successfully--and it appears I must have added too much liquid, but I could swear I didn't. (That's what bothers me most--that I thought I was quite careful about measuring.) But the dough started out like a batter. Figured, "no problem, I must have left out a cup of flour"--but now I've added TWO more cups of flour and it's still not coming together. Do I toss or try to salvage?
