Hi,

My sourdough isn't turning out as a nice boule shape. It seems to flatten after it's long proof on the bench (it's still quite active, as it rises/ flattens out in the oven) into a flattish shape. Am I not developing enough gluten in the initial mix? Something to do with humidity or temperature of proof? Starter activity? Old flour?

The bread still tastes quite good,with nice crumb structure; but it'd be nice to have a good shape. Any advice would be appreciated. I am using Rose Levy Beranbaum's The Bread Bible, basic soudough boule.

Thanks and Happy Baking,

Ryan
