Kalonji seeds, also known as Nigella seeds, black cumin, or black onion seeds, are tiny, black, tear-shaped seeds from the Nigella sativa plant, prized in cooking and traditional medicine for their slightly bitter, peppery flavor and potential health benefits like antioxidant and anti-inflammatory properties. They’re used whole or ground to flavor breads, curries, vegetables, and are rich in nutrients like fatty acids, protein, and antioxidants.  

Black sesame seeds are the unhulled, tiny, oval seeds from the Sesamum indicum plant, known for their richer, nuttier, slightly smoky flavor compared to white sesame, packed with calcium, protein, healthy fats, fiber, iron, and antioxidants, used widely in Asian cuisine for flavor, texture, and health benefits, including traditional medicine.
