Crusty bread almost too hard to slice can be placed into a food processor to make your own bread crumbs, says Maria Liberati, author of "The Basic Art of Italian Cooking." Add spices, salt and pepper as desired. Store bread crumbs in the fridge. They'll also keep for up to a month in the freezer in an airtight container. To save money by reviving soft crackers, Liberati suggests baking crackers for approximately three to eight minutes in an oven preheated to 350 degrees. And to keep cookies soft, store them in an airtight bag with a slice of toast.
