The 10 Commandments of Grilling

Thou shalt use fresh meats

• Slapping a frozen slab of meat on the grill makes for an uneven cook: the outside chars while the inside slowly thaws. For best results, you want to use fresh meats that went from the grocery store to your fridge, then straight to the grill. If you absolutely must use frozen, thaw them overnight in the fridge. Don’t even think about cooking those suckers until they are fully thawed.

Thou shalt not mistake the purpose of marinades

• The primary purpose primary purpose is to break down tougher meats (like flank and hanger steaks), to make them easier and more pleasant to chew.If you like the flavor of a marinade on a ribeye, cook that liquid down to a thicker sauce while your meats are cooking without it, then brush it on a minute or so before the end.

Thou shalt always clean thy grill

• Another “what the hell is wrong with you?” situation. A dirty grill leaves pieces of charred and carbonized last night’s meal all over this night’s dinner. That’s nasty. The best time to clean your grill is after you’ve preheated it -- just before you slap down your food. The fire will cook some of the old stuff away, and warm up the Klingons you can scrape them off easily.
