When the boss speaks.. you have to listenI am a mustard man use it on all my pork products. I like the way it helps the rub sick never had problems with taste or with bark since I have started to use the mustard. I first saw mustard used on ribs watching a bbq show on the food network some 8 years ago. This was before I had my ribs down like i do now. When i told my wife i was going to try this method she told me she woud not eat them. I made two rack of ribs the next smoke one with one without and she liked the one with mustard more. My rib recipie has evolved over the last 10 years all around what my wife likes. One day she finally told me don't change a thing and I haven't since.
