Nigella sativa seeds, often called black cumin or kalonji, are small, matte-black, triangular seeds with a pungent, slightly bitter, peppery-and-oniony flavor. They are used whole or lightly toasted as a finishing spice and a key component of several regional spice blends.
History & Origins
Nigella sativa was cultivated as early as the second millennium BCE, with charred seeds recovered from Bronze Age sites and from several pharaonic tombs, including that of Tutankhamun. It appears in classical Greek and Roman pharmacopoeias and is repeatedly cited in medieval Islamic medical literature, where it acquired the epithet "the seed of blessing." By the medieval period it was firmly embedded in South Asian, Levantine, and North African cooking and is now a global pantry spice.
