We've all been there; hell I was there for a pit stop last month ,Over-proofed again. I watched it like a hawk all day, checked it every half hour, dough rose about 65%. Went in the fridge overnight. Felt good about the dough last night. Dough temp was 73-72 degrees all day, so wouldn’t expect a ton of fermentation in the fridge on the final proof. But he we are again. I didn’t bake it long enough either as I like a thicker, crunchier crust. Tastes good, makes great toast. Another try next week.
You'll get it dialed it! When you say it rose 65% is that from end of stretch and folds or from first mixing in the starter?
