Master perfectly airy, delicate ciabatta bread at home. Made of the highest quality French stoneware, this pan helps you do it! Designed specially to achieve ciabatta's unique crumb structure. Here's how it works: The lid traps steam during baking to replicate the environment of a steam-injected oven. This steam allows the bread to expand fully, and also creates a crisp, crackly crust. Holds a recipe with 3 to 4 cups of flour. 15" x 9" x 1½" (makes two 14¾" long loaves).
