Final answer:
Burgers are typically cooked to a medium doneness, with an internal temperature of about 160°F (71°C), unless a customer specifies otherwise.
Step-by-step explanation:
Burgers are a popular and versatile food item enjoyed by people around the world. Typically consisting of a ground meat patty, often beef, that is seasoned, cooked, and placed inside a sliced bun, burgers can be customized with various toppings and condiments to suit individual preferences.
Unless a customer specifies, burgers are typically cooked to a medium doneness. This means that the internal temperature of the burger reaches about 160°F (71°C), which ensures that any harmful bacteria present in the meat are killed. Cooking burgers to medium doneness also allows for a juice and flavorful burger, without being too rare or well-done.
