I used this recipe to rub on a smoked turkey. This makes slightly less than double what the smoked turkey calls for, so you can have more for other uses or just cut this recipe in half and adjust the seasonings to bring it up to 1/2 cup total.

1/2 cup brown sugar
3 tablespoons smoked paprika
1 tablespoon black pepper
1 tablespoon salt
1 tablespoon garlic powder
1 tablespoon onion powder
1 teaspoon mustard powder
1/4 teaspoon cayenne pepper

Combine to mix.
