The large, open crumb that’s characteristic of ciabatta bread comes from a high hydration level in the dough as well as a poolish, which is a type of preferment (a fermentation starter or, sometimes, a “mother dough”) that gives bread a slightly nutty flavor and thin crust. Pile these rolls high with salami, provolone, and other Italian ingredients for perfect panini!
