Black Cumin (Nigella sativa)—also known as black seed or kalonji—is a small, jet-black seed known for its slightly bitter, peppery flavor with notes of onion, oregano, and nutmeg. It’s commonly used in Middle Eastern, Indian, and North African cuisines to flavor breads, pickles, curries, and vegetable dishes. Beyond the kitchen, black cumin is highly valued in traditional medicine for its immune-boosting and anti-inflammatory properties.
