cheese is melted, about 1 minute longer. The center of
the burgers should read 130°F for medium-rare, or 140°F
for medium. Assemble the burgers, topping them as
desired, and serve.
TO COOK UNDER THE BROILER
- Preheat the broiler to high. Place the patties on a foil-
lined broiler pan and position it so that tops of patties are
2½ to 3 inches below the broiler element. Broil until the
tops are well browned and beginning to char, about 3
minutes. Flip the patties and broil until an instant-read
thermometer inserted in the center reads 130°F for
medium-rare, or 140°F for medium, about 3 minutes
longer.
- Top each patty with a slice of cheese and place back
under the broiler for about 25 seconds to melt it. Place on
the toasted buns, topping the burgers as desired, and
serve.
