Brine proportions for a smaller turkey: Turkey sizes vary, so if you have a larger or smaller bird, go by these proportions instead: For every 5 pounds of turkey, you will need 1 tablespoon of kosher salt, 1/2 teaspoon dried herbs, and 1/4 teaspoon black pepper. Fresh herbs substitution: Instead of dried herbs, you can substitute 1 tablespoon finely chopped fresh herbs (or 1 teaspoon per 5 pounds of turkey).
