The kalonji, or Nigella seeds, is an interesting spice – when used for tempering, it adds a beautiful aroma to the dishes and a hint of flavour that you can’t quite nail. In India, dry roasted kalonji is used for flavouring curries, dal, stir-fried vegetables, and even savouries such as samosa, papdis and kachori among others. Flavour and aroma aside, the tiny black seed comes with a whole lot of health benefits. It’s loaded with trace elements, vitamins, crystalline nigellone, amino acids, saponin, crude fiber, proteins and fatty acids like linolenic and oleic acids, volatile oils, alkaloids, iron, sodium, potassium and calcium. It keeps your heart healthy, addresses breathing problem, lubricates your joints, and is known to have anti-carcinogenic properties.
