Botanical Information
Mustard comes from three Brassica species. Black (B. nigra) and brown (B. juncea) are pungent; yellow (S. alba) is milder. Pungency comes from glucosinolates broken down by myrosinase enzyme into isothiocyanates when seeds are crushed and mixed with water.
Origin & History
Native to the temperate regions of Europe, Asia, and the Mediterranean. Cultivated since 3,000 BCE. Romans called it 'mustum ardens' (burning must) — origin of the word 'mustard.' Dijon, France has produced fine mustard since the 13th century.
