SL rub has a lot of cayenne in it to me but I like hot,where did you hear they use kosher salt? The SL bottle I have you can tell they use table salt I got mine at barbeque galore a while back.
Nothing better, kosher salt and fresh cracked black pepper... some of the best brisket and ribs I have smoked have nothing but S and P on it... give it a try!!!!:thumb:
