This is an emergency! I've adapted the blueberry braid idea to a savory mushroom and onion filled bread. I'm using Pain de Campagne dough and I don't know how to adapt the baking time and temperature. Can a filled loaf be baked at the higher temperature called for with Pain de Campagne? Can the pain be baked at the 350 degree temperature at which the brioche dough is baked? Probably not- oh, I don't know.
