Final answer:
Evening out patties on a grill is important for consistent cooking and to achieve a uniform degree of doneness, ensuring food safety and quality.
Step-by-step explanation:
The purpose of evening out the patties on the grill is to ensure consistent cooking and to achieve the desired level of doneness across the entire surface of the patty. This can prevent areas from being undercooked or overcooked, which is especially important for both food safety and quality. Even thickness will allow the heat to distribute more evenly, preventing the patty from bulging in the center or having edges that might burn while the middle is still reaching the proper temperature. The goal is to have a patty with a consistent texture and flavor throughout.
