Fresh breadcrumbs are made from fresh bread processed down to crumb size. They are added to stuffings for bulk and to help them bind. They keep well in an air tight container in a freezer. This is a handy way to use up bread as you never know when fresh breadcrumbs will be required.
Dry breadcrumbs are made from bread dried in the oven, cooled and then processed in the same way as fresh breadcrumbs. These are used for coating foods prior to cooking, usually frying, helping to seal in moisture and providing a crisp crust.
