Bread Crumbs

Bread crumbs or breadcrumbs (regional variants including breading and crisping ) consist of crumbled bread of various dryness, sometimes with seasonings added, 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. The Japanese  variety of bread crumbs is called panko.

In the fairy tale "Hansel and Gretel", breadcrumbs are used by Hansel and Gretel to track their footpath. However, the bread crumbs were eventually eaten by birds, subsequently leading them to become lost in the woods. The popularity of breadcrumbs in the fairy tale led to the use of the word "breadcrumb" as a navigation element that allows users to keep track of their locations within programs or documents.
