In a bowl combine red raspberries, vinegar, lemon juice, garlic clove, mint, and olive oil. Split Cornish hens down the middle to flatten and arrange in a 13 x 9-inch shallow dish. Pour the marinade on top and let stand for 4 hours.
Grill, skin side down, for 10 minutes over hot coals. Turn and continue cooking for 20 to 25 minutes, basting frequently with the marinade.
