Some black and white mustard seeds. |
There's three main kinds of mustard seeds - black (strongest flavor), brown, and white (weakest). Yellow mustard is usually made of white seeds, with the darkness of the seed increasing with the strength of the mustard. The grinding of the seeds releases the flavor of the seed, and the yellow colour as well.
These three main mustard seeds discussed here originate from the Eurasian region, black more specifically from the Middle East. Interestingly, white mustard - Sinapis alba - is in a different family than black and brown mustards - Brassica junecea and Brassica nigra - which makes it even more unique as a weaker mustard. The more you know.
Mustard seed can also be used as a medicinal plant, as it has antibacterial properties. In fact, it has shown to treat rheumatism, including rheumatism arthritis. Mustard just keeps getting better and better, doesn't it?
A final, very surprising fact is that snowy Canada produces a whopping 43% (2005) of all mustard seed, followed by Nepal at 15% and a pack of other cold Eurasian countries. And here's me, thinking that mustard was a warm climate plant! But no, Canada is king of mustard. Now I know where I'm gonna live.
