What Is Black Mustard Oil?

What actually defines it

• Pressed from a darker, more pungent mustard seed, giving an oil with a sharper raw bite than the yellow variety.
• Traditional in Bengali and Eastern Indian cooking, especially fish curries, pickles and mustard based pastes and marinades.
• Usually cold pressed, kachi ghani style, which keeps the pungency and natural colour that refining would otherwise strip out.
• Heating it briefly to a light smoke before cooking mellows the raw sharpness, a step many traditional recipes build in as a first move.
• Also used as a natural preservative in pickling, where its pungency and oil content both help the pickle keep.
