Gaping Hole on the Bread Ceiling
I have been making Sourdough Ciabatta Rolls from wildyeastblog.com (Susan's Wild Yeast, http://www.wildyeastblog.com/2008/07/28/sourdough-ciabatta-rolls/). The first two attempts produced breads with wonderful crumbs and crusts. But the third gave me gaping hole on the ceiling of the bread(s). I am not sure I know what I did differently on the third attempt. Anybody knows why sometimes there are gaping holes on breads? Undeveloped gluten? Hydration problem?
