Grilling Procedure

Step 5

If using a charcoal grill, open vents on bottom of grill, then light charcoal. When charcoal turns grayish white (about 15 minutes from lighting), hold your hand 5 inches above grill rack to determine heat for charcoal as follows:

　　

Step 6

Hot: When you can hold your hand there for 1 to 2 seconds

　　

Step 7

Medium-hot: 3 to 4 seconds

　　

Step 8

Low: 5 to 6 seconds

　　

Step 9

If using a gas grill, preheat burners on high, covered, 10 minutes, then, if necessary, reduce to heat specified in recipe.

　　Cooks' note:

　　If you aren't able to grill outdoors, burgers can be cooked in a hot well-seasoned ridged grill pan over moderately high heat, turning over once, about 7 minutes total for medium-rare.
