Problem - large holes on top of loaves of bread
When I bake bread in a loaf pan I am getting a very large hole at the top of the loaf that goes almost the full length of the loaf. It is happening with whole wheat bread and sourdough bread.
I mix the dough in a kitchen-aid mixer. The dough rises in a bowl in my dishwasher. I then form the loaf by rolling out the dough into a rectangle and rolling it up. I seal the seam and place the loaf in a loaf pan. The bread then proofs in my dishwasher. Then bake.
When I cut into the loaf the large hole along the top is there.
What am I doing wrong?
