Hi, I hope to get some help here. Ok , I am a recent whole wheat bread baker, they were coming out fine but now seem to be falling after I rise them in a pan? Can anyone tell me why this happens?? and how to STOP it!! I work so hard and then pllluuuh, they are still edible but I yern for a nice high loaf to slice for sandwiches. I'm using vital wheat gluten, and suggestion would be great!!! 'THANKS!!!!!
