Brown Mustard Seed

Where it comes from

Brown mustard comes from Brassica juncea, sometimes called Indian mustard. The Himalayan foothills are its centre of cultivation, with India producing the bulk of the global crop. Canada also grows substantial brown mustard for the European condiment industry.

Flavor & pairing

The seeds contain sinigrin, which converts to allyl isothiocyanate — the same compound that gives horseradish and wasabi their sharp nasal heat. Hydration triggers the reaction; dry seeds taste nutty and quiet. Brown mustard suits fish, potatoes, cabbage, lentils, and bitter greens.

How it’s used

Indian tadka tempering pops the whole seeds in hot ghee or oil until they crackle and turn nutty, then tips them over dals, vegetables, and poha. Bengali kitchens grind them into a paste for fish curries like shorshe ilish. Dijon mustard pastes the cracked seed with white wine and vinegar.

Trade history

The black mustard (Brassica nigra) that once dominated French Dijon has been almost entirely replaced by brown, which is easier to harvest mechanically.
