What is Mustard Seeds?

Mustard Seeds are the small, round whole seeds of the mustard plant in the cabbage family (Brassicaceae). Several species are grown for culinary mustard: Sinapis alba (white or yellow mustard, the mildest), Brassica juncea (brown or Indian mustard), and Brassica nigra (black mustard, the sharpest). They are one of the oldest cultivated spices, used across many cuisines for thousands of years.

About the plant

The characteristic pungency of mustard develops only when the crushed seed meets water, which is why prepared mustards are mixed cold. Canada is the world's largest producer of mustard seed, which germinates best in cool, moist soil. The whole seed is a classic culinary spice for pickling brines, spice blends, and Indian and European cooking.
