Recently I was feeding Pierre (my starter :) ) and I had a bunch of starter to throw out. Hadn't baked all week due to a busy schedule. However I went about this as an experiement:
Add some flour (didn't measure) and knead briefuly to make a dough
Let rise for like 5 hours, then retard in fridge overnight
Take out, roll out very thin and dust with flour as needed.
500F for about 3-4 minutes and rotating for another 3-4 minutes (took two sheet pans)
turned out good and I thought I'd share in case anyone was really "throwing out" starter.
makes a quick snack throughout the day
