Mustard is a condiment made from the seeds of a mustard plant (white/ yellow mustard, Sinapis alba; brown/ Indian mustard, Brassica juncea; or black mustard, B. nigra). The whole, ground, cracked, or bruised mustard seeds are mixed with water, vinegar, lemon juice, wine, or other liquids, salt, and often other flavorings and spices, to create a paste or sauce ranging in color from bright yellow to dark brown. The taste of mustard ranges from sweet to spicy.
