If you want your turkey to taste like turkey (and not watered down turkey meat), The Food Lab's J. Kenzi Lopez Alt recommends dry brining with just salt. The other flavors probably won't penetrate the meat anyway, and the salt will help the turkey retain moisture.

There's a wonderful dry brined turkey recipe here on Food52: https://food52.com/blog... (I've made this and it's terrific.)
