Since my April post on this topic, I have embarked upon home baking sourdough loaves.
After two failures with starters, I now have a good one going which is now well over 1 month old.
I have made several passable and very tasty loaves from this over the last month, but the most recent one went wrong somewhere, but I don't know where.
Is there anyone with sourdough baking experience who can tell me why it would end up with enormous cavities, looking like this :-
