This is Biga Ciabatta following the formula in Reinhart's BBA (incidentally the only bread book I have right now). Turned out pretty well considering this was my first time making ciabatta and I messed up on the biga. I did not knead the biga at all and put it into the fridge after mixing and left it. Still came out great! Always a nice suprise. I also had to bake these on parchment on a sheet pan as I did not have a stone. I just got my stone yesterday so I'm eager to try it out!
