Mustard Seeds (राई / सरसों)

Mustard seeds are tiny, round seeds that pack a powerful, nutty punch when tempered in hot oil. They are a signature element of South Indian and West Indian 'Tadka,' adding a distinctive crackle and earthy aroma. There are two main types used in Indian kitchens: the smaller, pungent black seeds (Rai) and the larger yellow seeds (Sarson). In Bengal, they are ground into a sharp paste for iconic dishes like 'Sorshe Ilish.' The oil extracted from these seeds is a primary cooking medium in North and East India, known for its high smoke point. When toasted, mustard seeds release essential oils that enhance the flavor of simple lentils and vegetables. They are also a key preservative in Indian pickles, providing both flavor and shelf-life. Mustard seeds are native to the temperate regions of Europe but have been a staple in India for millennia. They symbolize fertility and prosperity in many regional cultures.
