Mustard Powder

Mustard powder is a fine, pale yellow spice ground from mustard seeds. Its pungency blooms when mixed with water, delivering a sharp, nasal heat that softens with cooking; it emulsifies dressings, seasons dry rubs, builds spice blends, and sharpens sauces.\n\nCultivated from Brassica species native to the Mediterranean and South Asia, mustard spread through Europe and the Americas via trade and farming. Cooks in British, French, Indian, and Chinese cuisines grind seeds into flour or powder for condiments, pickles, and spice blends.
