Mustard seeds, from the mustard plant (Brassica juncea), are small, round or oval seeds that are usually dark brown in color, although they can also be yellow, white, or black, depending on the mustard variety. They are widely used in cuisine around the world and have a unique, pungent flavor profile.
Mustard seeds have a crunchy texture when chewed, but their real distinguishing feature is their hot, spicy flavor. When crushed, ground, or steeped in liquid, they release their characteristic spiciness. This sharp, slightly bitter heat is due to chemical compounds in the seeds, including isothiocyanate. Mustard seeds are commonly used to spice up dishes, but they can also be used for their crunchy texture.
