The Tuscan is the simplest of all grills, a sturdy metal grate with legs, so you can position it over a fire. Italians in general and Tuscans in particular use these grills in their fireplaces. You let the wood or charcoal burn down to embers and shovel them under the grate. The food goes on top. More elaborate versions feature a double grate attached at one end with a hinge. You place your steak or portobello mushrooms between the grates and turn the device over when one side is grilled.
What to look for when buying a Tuscan grill: Sturdy construction; legs that raise the grill at least 4 inches above the floor of your fireplace; and grates with variably spaced bars that can hold both large and small pieces of food.
