This last weekend, I didn't have any rub made up or store bought. So I just seasoned my baby backs with a a little lawrey's, pepper, pepprika, anda touch of garlic and onion powder. Just sprinkled it on. Didn't use any sugar. After 4 hours, i brushed them with a little honey then sauced them about 15 min at the end. They were the most beautiful mahogany color and the taste was just perfect.. I am always looking for the perfect rub but in reality keeping it simple is what yielded the best ribs to date. Cooked them low unfoiled like I always do 250 ish.
