Mustard is one of the oldest spices used in the world. It's pungent and spicy on the nose, but that heat can be abated with a little acid. Use mustard powder in dressings and sauces, in rubs and spice blends, or mix with water and vinegar to make your own mustard sauce. Add yellow or brown mustard seeds to your sauce for extra texture and heat.
