Steven Raichlen, host of TV's Barbecue University, has written dozens of books on grilling. Here, he distills a library of advice into 10 simple tips to mastering the grill.
Plus: Quick Grilling Recipes
1. Grill over wood
Forget about the gas-versus-charcoal debate: Wood is the only fuel that adds real flavor to food. If possible, use whole hardwood logs in a wood-burning grill. The next best option is to burn hardwood chunks in a regular grill. (Light them in a chimney starter as you would charcoal.) As a last resort, toss some wood chips onto the coals of your charcoal grill--you use hardwood charcoal, right?--or in the smoker box of your gas grill just before you begin grilling.
2. Keep your cool
You don't need to bring steaks to room temperature before grilling: There's no appreciable difference in cooking time. Steak houses keep meat refrigerated until they're ready to cook it--for reasons of convenience and food safety--and so should you.
3. Line it up
Align the food on your grill in a neat row with soldierly precision. This helps you keep track of which foods went on the fire first, so you can turn them and take them off in order. Plus it looks more professional--and looking professional is half the battle.
4. Flip just once
You can't get killer grill marks (the signature of master grillmanship) or accurately gauge cooking time if you're compulsively turning over your steak every 10 seconds. To lay on a handsome set of crosshatches, rotate the steak 90 degrees after a couple of minutes of grilling.
5. Season before grilling
You might have heard that salt "bleeds" the juices out of raw meat: It doesn't. Instead, it helps steaks form a savory crust as they cook. Just before putting the steaks on the grill, sprinkle on a generous amount of coarse salt and freshly ground black pepper.
6. Keep the grate hot, clean and oiled
This is the grill master's mantra. Following it will prevent food from sticking and give it excellent grill marks. Before grilling, scrub the hot grate with a wire brush, then rub it with a tightly folded paper towel dipped in oil. Scrub the grate again when you're finished cooking.
7. Grill your veggies
The dry heat of a grill intensifies a vegetable's natural sweetness. Grill tender, watery vegetables, such as bell peppers and onions, directly over the coals. Grill dense or starchy vegetables, such as sliced potatoes and eggplant, using indirect heat, as far away from the coals as possible.
8. Grip, don't stab
Use a pair of tongs--not a barbecue fork or, worse, a knife--to turn meat or move it around on the grill. Forks and knives poke holes in the meat that can allow precious juices to drain out. If you must cut and peek to check doneness, make a small slit with a knife.
9. Know when it's done
For steaks, chops and chicken, poke the meat with your finger: If it feels soft and squishy, it's rare; yielding, medium-rare; only slightly yielding, medium; firm and springy, well-done. For large cuts of meat, use an instant-read meat thermometer (even barbecue pros use them). Just don't let it touch any bones, or you'll get a false reading.
10. Let it rest
When you grill a piece of meat, its muscle fibers contract and drive the juices to the center of the cut. Meat served right off the grill will taste tough and dry, but a post-grill rest allows the muscle fibers to reabsorb the juices, resulting in a tender and succulent cut. Larger pieces of meat, like leg of lamb and pork shoulder, need to rest longer than steaks and chops--for approximately 15 minutes.
