(not that kind of pork rub)
I tried searching the boards for this but - like the fourth son - I couldn't figure out how to phrase the search. What does a rub do? How does it work? I'm grilling a pork tenderloin tomorrow night and in the past I've just marinated it, but the guy sold me on a rub, so now I'm trying to figure out how to use it. Do you marinate then rub? Marinate in the rub? How should I prep it differently than just marinating and throwing it on the grill?
