Mustard Seedsसरसों (Sarson) / राई (Rai)
Properties
Mustard seeds are the small round seeds of various mustard plants, most commonly Brassica nigra (black mustard), Brassica juncea (brown Indian mustard), and Sinapis alba (white/yellow mustard).
They are characterized by their sharp, pungent flavor, which is released when the seeds are crushed and mixed with liquid, activating the enzyme myrosinase. Mustard seeds are a staple in Indian cooking (especially for tempering or tadka), pickling, and global condiment production.
