Nigella seeds are small, matte-black, triangular seeds with a faintly bitter, oniony, peppery aroma, used whole or lightly toasted as a finishing spice. Despite the common name 'black cumin,' they belong to the buttercup family and are unrelated to true cumin or caraway.
History & Origins
Nigella sativa has been used as both a food and medicine for over three millennia, with seeds found in the tomb of Pharaoh Tutankhamun and referenced in ancient Egyptian, Greek, and Roman texts. In the medieval Islamic world, the seeds were prized in Arabic pharmacopoeia and often carried in medicinal confections, while Indian Ayurvedic practitioners incorporated them into digestive and respiratory remedies. The spice spread along trade routes into South Asia, where it became an integral component of Bengali panch phoron and Punjabi naan toppings.
