Yellow Mustard Seed (also called White Mustard Seed) is botanically called Brassica alba (sometimes identified as Sinapis alba or Brassica hirta) and is from the family Brassicaceae. Other members of this family include black mustard, brown mustard, horseradish and wasabi. Ground mustard is added to sauces for fruit and in India cooking the seeds in hot oil enhances the nutty flavor before adding it to chutneys, curries, and sauces. Mustard seeds are also popular in pickling spices.
