This recipe works on a small portable grill (12 inches in diameter or larger). If you’re not going to be at your gathering long, a portable gas grill is preferable as you won’t have to worry about letting the charcoal cool down. If you are using a charcoal grill, prepare the coals as you would a full-size grill by banking in the center to light (or using a chimney starter). Most small grills have a line inside that show the maximum amount you can fill them, about halfway up. Let the charcoal cool completely before disposing of the coals. If you need to pack up before your coals are cool, dump them into a fireproof vessel and douse with water until completely out, then dispose of the coals.
