I have been baking bread for a few years and using the Bread Bible the past 3 years. My best is the Jewish Rye, Raisin, and Ciabatta. I used to be able to turn out a really good Hearth Bread too, but recently (the last 6 months) I just can’t seem to succeed in baking a decent loaf of hearth bread. I always double the book’s recipes (except for raisin bread). My hearth bread develops huge bubbles on the top. If I slash the bread before baking it collapses. I use King Arthur Bread and whole wheat Flour according to the recipe. I mix it in a Kitchen Aide using a dough hook. I use the amount of water called for in the recipe (doubled) although I notice that at the end of the recipe it references 1.5 cups, not 1 1/3 cups. What could I be doing wrong now that I didn’t used to do wrong?
Thanks for any tips.
