Thoroughly wash Cornish game hens. Combine the rest of the ingredients. Place the clean hens in a extra large Ziploc storage bag and pour combined ingredients over the hens. Seal bag and gently massage the bag to ensure that the marinade is well distrubed. Place the bag in a 9 x 13 in pan and place in the refridgerator for 12 - 24 hours. Occasionally turn the bag during the marinading time.
