I don't brine unless it is a fresh bird most birds are already brined at the processors. I do inject with Creole butter sometimes( good product) and sometimes I just melt some unsalted butter and steep some Tony C's in it and inject that. I never inject a bird that I have brined. Keep it simple and let old Tom be all he can be.
