Notes
This dry BBQ rub has a subtle smokey flavor to it. Don't worry it's not overwhelming just a subtle hint. It comes from smoked paprika but if you don't like it don't worry just omit it. It will still taste great without it.
Also, this rub is very customizable. If you want more heat feel free to up the amount of cayenne pepper. If there is a spice you really don't like just omit it or replace it with something similar. Having said that don't substitute the dark brown sugar or the kosher salt. Both are vital components of a basic sweet rub.
