My Bird Brine, Rub and Injection

[Andy M.]

Brining an enhanced turkey will not make it any saltier than the average of the two - the brine or the enhancement.

When you brine, liquids pass back and forth through the cell walls striving to create an equilibrium - that is, the saltiness is equal inside and out. So, if the fluids in the turkey's cells have a lower salt content than the brine, the two will equalize until the fluid in the cells and in the brine are the same.
