My employer is kind enough every year to provide each employee a turkey for the thanksgiving holiday. I cook it every year and have always had good results but I am looking for great results and with all the talk over the last few years of brining I was going to give it a try this year. But I read somewhere that one should not brine a pre-frozen turkey, that there is already a mild brine solution on the bird. What are your guys thoughts on brining a pre-frozen, commercial processed bird.

Thanks!
