My first was Bad Byron's Butt Rub. However, I have gotten creative lately. I made my own rubs a few times. I am not a big fan of salt, so making my own is much more satisfying. Ground ginger, fine ground dark roast coffe, ancho chile powder, cayenne, chili powder, black pepper, brown sugar, onion powder, garlic powder. Just a few ideas to throw together yer own rub. Happy smoking!! Also, a boston butt all by itself has some amazing flavor!!
