Final answer:
Crust formation and browning occur during the cooking process and are primarily associated with food preparation.
Step-by-step explanation:
Crust formation and browning occur during the cooking process and are primarily associated with food preparation rather than academic subjects. When cooking food, crust formation occurs when heat is applied to the outer surface, causing it to brown and become crispy. This process is commonly seen in baked goods, such as bread or pastries, as well as in roasted meats and vegetables.
