Place all dry ingredients in a large container, big enough to hold a turkey
Mix dry ingredients with water until everything is dissolved
Place turkey in the brine and let it soak for 48-72 hours under refrigeration or in an ice chest covered with ice. Top off with water if the turkey isn't completely submerged
Notes
Curing salt can be a very dangerous chemical if ingested by itself. Always read the instructions on the package before use. If you are uncomfortable using curing salt, or you just don't have any, feel free to omit it from the recipe!
