They seem to be everywhere I look these days. Every time I turn around, there's another one of those gleaming, stainless steel gas grills. At my hardware store, of course, but they're even in the center aisle of my grocery store. And as if some higher barbecue power were deliberately taunting me, I think for the last two weeks every other pickup truck I've been stuck behind in traffic has had one of those big boys strapped down in back. It seems like you can't really call yourself a cook anymore unless you've spent a couple of grand on a grill.

I don't know about you, but every time I see one I have an uncontrollable impulse to run out and buy another bag of charcoal.

Then I go home, light a little fire in my old kettle grill, and 20 to 25 minutes later I'm ready to cook something delicious: a butterflied leg of lamb marinated in yogurt and Indian spices, a whole chicken flattened and cooked under a brick so it's crisp and juicy, and even hickory-smoked spice-rubbed pork ribs so good they don't even need sauce. ¶ Grilling is essentially a simple art, and the only thing all that fancy equipment does (aside from giving you flashy new toys to show off) is add a modicum of convenience.

I'm more of a back-to-basics guy, especially when the basics are so simple to master. Buy a grill (a really good one will cost less than $150). Add a charcoal chimney (a sure-fire way to light coals quickly) -- and maybe one or two other little things -- and you're ready to go.

In exchange for that simplicity and cooking quality, there are a couple of things you have to think about when cooking with a live fire. The first, of course, is the fire itself. The tendency is to fill the grill with as many coals as will fit. This works well if you're starting a blacksmith shop, but cooking requires a more deft touch.

In most cases, you'll want to use only a chimney full of coals, and unless you're grilling thin, quick-cooking food such as vegetables, flank steak or fish, arrange the coals so they're sloped against one side of the grill. This gives you two temperatures to work with -- very hot directly over the fire and somewhat cooler away from the flame.

Use the very hot side to sear the meat and then move it away to cook through. I've even started cooking steaks this way. Unless you're looking for black-and-blue (charred outside, raw inside), you'll get a more moist, more evenly cooked piece of meat by doing most of the cooking over a cooler fire.

Even better, this also discourages those raging flare-ups that are the bane of every grill cook. Because the high-heat cooking that renders fat happens early, by the time the flare-ups get bad, the meat should be safely away from the fire.

This is particularly true for fatty meats like chicken with the skin on. Grill the chicken under a brick over the direct flame and you'll wind up with charred skin and raw flesh. Let it go more gently over indirect heat, though, and the skin turns golden and crisp while the meat stays moist and juicy.

This is the classic Italian pollo al mattone. I have never found an acceptable explanation for why cooking a flattened chicken under a brick would make it taste so wonderful, but there's no arguing with the results.

A burning question

WHICH coals: hardwood or briquette? That's a question that can inspire hours of debate. The truth: It doesn't make all that much difference. Hardwood charcoal is better for most grilling, because it burns somewhat hotter and cleaner (there's very little ash left after the fire dies).

But for meats such as pork shoulder or spareribs, you're going to need the fire to cook low and slow for a few hours, so using longer-lasting briquettes will spare you the need to refuel.

Marinades are another area of controversy. They're a point of pride for some cooks, who think that there's nothing like a long soak in an herb-scented tub to improve a piece of meat.

In most cases, that's the wrong way to go. You're better off with a short dip.

The fact is that most marinades never penetrate much beyond the surface of the meat. And really, that's enough. Most of the meat we grill is fairly thin anyway, so you're very likely to have a bit of the flavored surface in every bite.

The problem with long soaks is that if the marinade contains any acidity -- lemon juice, vinegar, even the lactic acid in yogurt -- it will break down the protein structure of the meat, resulting in a mealy texture.

When I cooked the leg of lamb in yogurt and spices the traditional Indian way, marinating the meat overnight, the outside of the lamb seemed somewhat pasty in texture. When I cooked it a second time, amping up the seasoning a little, but marinating for only about an hour, the flavor was just as good and the texture was firm and meaty.

One exception to this marinade rule is brining. Brines (basically salt-water solutions) keep meats such as chicken and pork moist during cooking, and because they contain either very little acidity or none at all, they don't break down the meat.
