So I made the 1200 grams Miche today, now cold proofing.I was going to take picture but my grandson came over (he is autistic) who is in high school. He loves to watch the dough making process but does not want to touch it. So he said he would take pictures and videos. He took pictures, of my floor, the dog, through the doorway to see the dough proofing. So no pictures. Anyways when it was time (I think) to pre shape it had big bubbles I pinched them then pre-shaped. After 30 mins went back to due to finial shape, huge bubbles. I pinced them but as I am trying to get this shaped tighter I am getting more and more bubbles. Is this normal? I have had bubbles before but not like this, one right after another. Did I let it go to long?
