When smoking pork ribs I like to pour or slather stuff on the racks for different layers of flavor. A good rub that is not heavy on the salt, Coca Cola, apple/pineapple juice combo, Tiger sauce, butter, brown sugar, pineapple/habanero glaze and homemade barbecue sauce at the end. Sometimes I only use a couple of things. Just according how I feel and how elaborate I want to get. It just works for me. I wanted to hear for some of you about what you do as it relates to different flavor layers. Have a good one!!
