Mix garlic, salt, peppercorns, coriander and lemon juice and rub into the chicken breasts. Cover and stand for at least one hour or overnight in refrigerator. Put under a hot grill about 6 inches from heat. Cook, turning every 5 minutes until chicken is tender and skin crisp. Serves 4. NOTE: Especially good cooked on the barbecue.
