Hey all. It's been a while. Glad to be back. I'm smoking an 18 lb. turkey and using a 5 gallon bucket for my brine. Most of the recipes I see for brines call for only a gallon or galllon and a half of water. This turkey is so big that I need about two or two and half gallons of water to fully submerge it. Should I add more salt and sugar and double the recipe? Or does it matter? Thanks for the help.
