Black Mustard vs Yellow Mustard Seeds

The seed comparison behind the oil comparison, and how it shows up when they are pressed instead of tempered whole.

Black and yellow mustard seeds differ the same way their pressed oils do, sharper against milder, and that difference shows up whether the seed is tempered whole or pressed into oil.

What actually differs

  • Black mustard seeds are smaller and sharper in flavour, the classic tempering seed in Eastern Indian and Bengali cooking.
  • Yellow mustard seeds are milder and larger, more common in pickling spice blends and some North Indian preparations.
  • Both pop and release aroma quickly when added to hot oil, black doing so more assertively than yellow.
  • Colour follows the same pattern as the oil, black seeds are visibly darker than the pale yellow of the milder variety.
  • We press both into oil rather than selling the loose seed, so the pungency difference described here shows up most directly in our black and yellow mustard oils.
