There are two types of breadcrumbs: dry and fresh. Both can be made with day old or stale bread, both are easily frozen and can be used from frozen (no need to defrost), and both can be used as a breading for baking or frying. The main difference is that fresh breadcrumbs are used as a binder for recipes like meatloaf and meatballs whereas dry breadcrumbs are used to add a crunchy texture or toppings to dishes like casseroles and baked pasta dishes.
