Dr. GONZO's XX Mustard Plaster XX is delightfully thick, all natural, honey mustard with a serious kick. Laced with whole mustard seeds, our XX Mustard Plaster XX is great on any deli sandwich, grilled sausage, used as a ham glaze, grilled chicken marinade or eaten straight from the jar on pretzels or apple slices. Contrary to what your grandmother will suggest, the “Good Doctor” recommends internal use only with this product. Do you have a sandwich heading for disaster? Trying to become a Barbecue Master?
