What does crusted mean?
"Crusted" means covered with, or formed into, a hard outer layer known as a crust. It most often appears as an adjective describing surfaces coated with something that has dried and hardened — mud on boots, blood on a wound, frost on a window, or salt on skin after swimming. It can also describe foods such as bread or pastry that have developed a firm, baked exterior, and it functions as the past participle of the verb "to crust," which itself derives from Latin "crusta," meaning shell or rind. The word's connotation depends heavily on context: crusted dirt or residue suggests neglect or hardship, while a crusted loaf or pie suggests appetizing texture. Common patterns include "crusted with mud" and compounds like "snow-crusted." Related forms include the noun "crust," the adjective "crusty," and the intensified term "encrusted," used for decorative layers such as jewels or gold.
Covered with or formed into a hard outer layer, typically of dirt, dried liquid, ice, or baked material.

Most commonly used with 'with' to specify what forms the crust.
Past participle of the verb 'crust': having formed or acquired a hardened surface layer.

Etymology of crusted
"Crusted" derives from "crust," which comes from Latin "crusta," meaning shell, rind, or hardened surface. The Latin word entered English via Old French "croste" during the medieval period, and the verb "to crust" and its participle "crusted" developed from it. The same Latin root gave rise to "custard" (originally a pastry shell) and to "incrustation," making these genuine etymological relatives rather than coincidental look-alikes.
