Indirect, but straight forward!
This technique belongs to very basics of great grilling. Luckily, it is the simplest thing to learn. Indirect grilling means keeping the meat away from the direct, radiant heat. This requires arranging two grilling zones inside your grill. In practice, you split the grill in half and place charcoals on the other side, while another half remains empty. Some pitmasters call this arrangement "half and half". This is also something you use when reverse searing your steak. Read about reverse sear here.
If you are cooking with a gas grill, you need to have a model with several burners split in minimum two zones.
Why indirect grilling?
Indirect grilling gives you better control over temperature, thus greater cooking results. When cooking on two zones, the empty side is called cool zone and the other side hot zone. Meat goes always on cool zone where heat travels through air from the hot zone.
This is important especially when grilling larger cuts of meat. Just imagine cooking 3lb (2,7kg) pork loin directly on top of the burning hot charcoals for an hour. Most likely you would get burned surface and under cooked interior. Gentle heat through convection is key to success.
Surely you will need direct heat for grilling also. Searing is another technique, but then you work on high heat and short periods. That’s another story.
Now go grilling, indirectly!
