I'm in the middle of brining 4 turkey breast halves (3 lbs each for a total of 12 lbs). I know that the general rule is 1 hour of brining for 1 lb. of turkey - so does this mean that I need to do it for 3 hours or 12 hours? I think 3 hours would be right because each breast half is about 3 lbs - but I'm looking for the expert opinion out there. Thanks y'all for the help.
