Black cumin seeds, also known as nigella seeds or kalonji, are small, triangular seeds with a distinctively bitter and peppery flavor. They are rich in protein, fiber, vitamins (particularly vitamin C), and minerals (such as calcium and iron). Black cumin seeds are widely used in Indian, Middle Eastern, and North African cuisines for their aromatic and medicinal properties. They are often sprinkled on breads, savory pastries, and salads, and used in spice blends and pickles. Black cumin seeds offer potential health benefits, including digestive aid, anti-inflammatory properties, and supporting immune function.
