Nigella sativa, commonly known as black cumin or Kalinji, is a plant whose seeds are valued for their aroma and beneficial properties. These seeds, which are mature, clean, and dried, contain notable amounts of essential oils, including linoleic acid, and bioactive substances like thymoquinone, which has been used in treatments for food allergies. When cooked, their unique flavor, reminiscent of nuts, can add a special nuance to various dishes. Native to India, these seeds are darker and sweeter than traditional cumin and should be used in small amounts to avoid an overpowering taste. Proper storage of the seeds is crucial; it's recommended to keep them in a cool, dry place away from direct sunlight and other strongly scented products. Caution is advised, as although they are NOT a gluten ingredient, they may contain traces of tree nuts, celery, mustard, and sesame due to cross-contamination.
