,Hi,
I have been smoking from 75 to 100 lb of turkey per year for the past 25 years. I use a sweet brine 1/2 salt and 1/2 sugar. I make the brine strong enough to float a small raw potatoe. I usually add 2 tbs of onion powder and 1 tsp of ground sage per gallon of brine. I break down the turkey into wings, legs (drumstick & thigh together), and breast (broken into right and left sides). The breast portions are encased in elastic mest. Then, the legs and breasts are pumped with brine (wings are thin enough that they don't need pumping) and the meat immersed in brine in a refrigerator for 48 hours. I don't use nitrates because nitrates/nitrites were historicaly used to prevent trichinosis in pork. If I want the final product to have a pink colour I add 1 tsp of ascorbic acid (vitamin C) per 10 lb of product. After 48 hours I rinse the pieces to remove the surface salt, hang in my smoker with the vents open until the product is dry, cold smoke at 100 degrees for at least four hours, and then raise the temperature 10 degrees per hour, while continuing a light smoke, until the interior temperature of the thickest piece is 155 degrees.
