Brining a turkey before cooking keeps the meat moist. For a medium size turkey (12-15 lbs.) about 1 lb. of brine mixture is needed. The proportion is 2 gallons of water to 1lb. of mixture. Put mixture and water in a large pot and bring to a boil. Remove from heat and allow to completely cool before adding turkey. Turkey should sit in brine overnight (12 hours is best) in a refrigerator.
Wash turkey and discard mixture before starting preparations to cook.
