Name and origin
Mustard is one of the most diverse and important cultivated crops on the planet. The genus Brassica contains not only mustard but also: Cabbage, Brussels sprouts, Broccoli, Cauliflower, Kale and Turnips. The genus name Brassica comes from the Latin for cabbage. The common name mustard is thought to come from the Latin words Mustum, referring to the unfermented grape juice used to stabilise the condiment, and Ardens meaning hot or flaming. The three main species of Brassica which are grown for Mustard seeds are Yellow Mustard (B. hirta) , Brown Mustard (B. juncea) and Black Mustard (B. nigra).
The seeds can be used whole, ground into a fine powder or hydrated with water or other liquids to activate the hot pungency which mustard is known for. The hydration and preparation methods vary between different country’s traditions. The pH and temperature of the hydrating liquid can significantly alter the flavour profile of the eventual paste.
Mustard has been cultivated for thousands of years with evidence of its use as far back as 1850 BC in the Indus valley region of the Indian subcontinent.
