Why does this happen? (Photo inside)
I've been attempting sourdough for awhile now and my results are pretty much always terrible! I'll bake bread using instant yeast and have fine results but sourdough just never seems to work for me. I've tried stretch and fols, and slap and fold. High hydration and moderate. This one was following the classic 3-2-1 ratio. I'm getting disheartened, it's frustrating and through all of my searches online I can never find an adequate solution. Almost every single loaf has a dense crumb with big pockets in it. Please offer some guidance!
Thanks in advance!
