Black mustard is the smallest of the mustard seeds and is oblong in shape. Black mustard seeds have a well deserved reputation for their pungent spicy aroma and flavor. Most common in Indian cooking black mustard seeds are often fried in oil, making them sweet and mild while releasing a nutty aroma.
