Do not pick the carcass completely clean of meat. The extra meat will add more flavor to the stock. If there is any skin leftover, use that as well. Any fat accumulated after cooking can be saved for future use. Also, this base recipe calls for a carcass from a 12-14 pound turkey which should yield about 4-6 pounds of bones and bits. If you have a larger turkey carcass, adjust the amount of water; about 1 1/2 cups per pound.
