Dough begins to break down!
Ok, I've been making bread several months and have not encountered this until I've become overly ambitious. I have a problem that started folding some dough that I stashed in the fridge for several hours, now with dough I'm kneading on the first go. It seems to begin to break down?! It goes from being elastic and having surface tension, to being a very slack, non elastic, stringy, taffy-like substance. What have I done?!
