I have smoked and brined a lot of things but this brine for a turkey breast bye far is the best I have used if you like sweet things.
In a 2 gallon ziplock bag in a pot put 1 5-7lb turkey breast 1 gal water, 1 cup salt, 1 1/2 cups brown sugar, 1 tbls Rosemary,thyme and allspice, 1/8th cup molasses, white wine and Worcestershire sauce then brine for 12 hrs and smoke with apple wood at the end I put corn on the cob on the grill.
