Not unlike coriander, the Yellow Mustard Seed is a very versatile spice. It can be toasted to be added to dishes, used for pickling, or ground to make mustard condiments. Mustard has warm earthy tones with a nutty complexion, and is a superb meat companion, especially poultry. It has a very short lifespan, though. It loses its potency quickly, so best to buy whole and toast and grind as needed.
