The ingredients for one gallon of brine are:
1-2 cups of salt
1 gallon of water
32 oz of apple juice
2 cups of brown sugar
1 tbsp whole pepper corns
3 bay leaves
16 oz of pure honey
Anything you add to brine will influence the taste of the turkey.
Step 1: Making the Brine
You need to make enough brine to cover the entire turkey. To make the brine get a pot big enough to hold entire turkey with brine, place one gallon of water in pot and add one cup of salt. Mix until salt is dissolved completely then place whole uncracked uncooked egg in solution (this is just to test and will be removed). If egg floats add salt until the egg floats. Make sure to keep up with the amount of salt added and if one gallon of brine does not completely cover turkey then repeat until turkey is covered.
After you are sure turkey is covered remove turkey and add all oter ingredients mixing well. Replace turkey in pot and refrigerate for 12 to 24 hours (the longer the better).
Step 2: Smoking the Turkey
When tempature reaches 155 degrees remove turkey cover with foil. The last 5 degrees will be made up while turkey sits as turkey will still cook until it is cool enough to eat. Very Important let turkey rest for at least 30 min.
Meat will have a pinkish-red hue and a black skin no matter how it looks after this it is going to be good. I will garantee that if you do this exactly as I say then this will be the best turkey you have had.
