I'm baking ~67% hydration bread, following this recipe Kvali food dutch oven bread. The bread is baked using a covered cast iron casserole dish heated to 250'c, and following the cooking times suggested in the recipe.
However, the bread is developing a crust that is "sucky" rather than either chewy or crunchy. It pulls moisture from the mouth and ends up unpleasant to eat - despite having blisters.
This effect gets worse the longer wait to eat the bread - it's bearable straight out of the oven but after an hour or so is a major detractor from the bread experience.
