2. Combine garlic, wine, thyme, salt and pepper. Pour marinade into a plastic bag and add cornish halves. Close the bag tightly, removing air so that cornish is covered by marinade. Marinate for several hours or overnight, under refrigeration.
3. Broil cornish halves 6-inches from heat for 25 to 30 minutes, turning several times.
4. If you prefer to grill them, it will take about 35 to 40 minutes over medium coals.
