There are several synonyms for the term "bread crusts," including bread heels, crusty ends, and crust trimmings. Bread heels are the slices at the end of a loaf, which are often considered less desirable than the bread's softer interiors. Crusty ends refer to the firm, golden-brown outer layer of bread, which is formed during the baking process. Lastly, crust trimmings describe the excess crust that may be removed before or after slicing to create a more uniform appearance. While some may discard bread crusts, they can be repurposed in recipes like breadcrumbs or transformed into a savory snack with toppings like cheese or hummus.
