Compared to yellow mustard, black mustard is less spicy and it tastes more bitter. In cooking, it is often combined with fatty meat to mitigate its taste. It is mixed with vinegar, water and other ingredients to make mustard sauce.
Belonging to a perennial herbaceous plant, mustard seeds are small, hard, smooth and spherical grains. Depending on the variety of the plant, seeds can differ in colour and
shape: Brassica alba has larger, yellowish-white seeds, while Brassica nigra has smaller
brown or black seeds.
