*My grandma saved the crusts from loaves of white bread by tossing them in a roasting pan stored in the oven where they dried out. When she needed crumbs or filled the pan, she hand-grated the dried crusts on a box grater. If you have stale bread (or want to dry slices in the oven), just pulse them in a food processor. Its fast and efficient. I often use dried, unseasoned breadcrumbs from the store.
