What should you hear when placing a raw patty on the grill to indicate that it is hot enough?

When placing a raw patty on the grill, you should hear a sizzle. This sound indicates that the grill has reached the appropriate temperature to cook the meat effectively. The sizzle signifies that the moisture in the beef is rapidly evaporating and that the surface of the patty is beginning to sear. This searing is essential for developing the rich flavors and textures associated with properly grilled burgers. A consistent sizzle assures the cook that the patty will not only cook evenly but also maintain its juiciness. Hearing this sound is a good affirmation of the grilling temperature and technique being used.
