Seam side up not splitting
Hi all. Been baking in cast iron pots for years now. I learned to put the boules in the pots with the seam side up and not score the loaves, instead look for that natural crust slash. I love that rustic look.
Well, ever since I moved to baking in cookie sheets in a professional oven with proper steam function, my loaves rarely split like they used to. (Check pic)
I do preheat the baking sheets and add good steam at the start of the bake. Am I gonna have to start scoring my dough?
Clues? Advice?
muchas gracias,
Bryan.
