Heera Kalonjee are aromatic black nigella seeds (also known as kalonji), known for their slightly bitter, earthy flavor with a hint of onion and oregano‑like notes. They’re perfect for tempering dals, curries, pickles, parathas, and breads. They can also be used in spice blends or sprinkled over salads and vegetable dishes to add a distinctive flavor and aroma.
