To make dry bread cubes, cut fresh bread into 1/2-inch cubes. (18 to 21 bread slices will yield 12 cups cubes). Preheat oven to 300 degrees F. Spread cubes in two 15x10-inch baking pans. Bake 10 to 15 minutes or until dry, stirring twice; cool. (Cubes will continue to dry and crisp as they cool.) Or let bread cubes stand, loosely covered, at room temperature for 8 to 12 hours.
