Pangrattato (Italian for ‘breadcrumb’) is a flavoursome and crunchy Italian breadcrumb topping, particularly nice as an addition to risotto or pasta dishes. It’s easy to put together and a great way to use up old, stale bread.

Breadcrumbs are small particles of dry bread, used for breading or crumbing foods, topping casseroles, stuffing poultry, thickening stews, adding inexpensive bulk to soups, meatloaves and similar foods, and making a crisp and crunchy covering for fried foods, especially breaded cutlets like tonkatsu and schnitzel.

Dry breadcrumbs are made from dry breads which have been baked or toasted to remove most remaining moisture, and may even have a sandy or even powdery texture. Bread crumbs are most easily produced by pulverizing slices of bread in a food processor, using a steel blade to make coarse crumbs, or a grating blade to make fine crumbs. A grater or similar tool will also do.

The breads used to make soft or fresh bread crumbs are not quite as dry, so the crumbs are larger and produce a softer coating, crust, or stuffing. The crumb of bread crumb is also a term that refers to the texture of the soft, inner part of a bread loaf, as distinguished from the crust, or "skin".
