Nigella

Nigella sativa · kalonji · kalo jeere

The seed of blessing — black, sharp, and quietly everywhere.

What it is

Nigella is a small, matte-black, angular seed with a sharp, faintly bitter, oniony taste. Despite two common nicknames it is neither an onion seed nor a true cumin — it comes from a flowering plant of its own. Whole and untoasted it is peppery; bloomed in oil it turns nutty and mild.

Where it comes from

Grown widely across South and West Asia, nigella carries deep cultural weight in the region and beyond — it is the “seed of blessing” of the Islamic world, and a fixture of both Bengali and wider subcontinental cooking.

What it's called

Nigella · kalonji (Hindi/Urdu) · kalo jeere (Bengali) · habbat al-barakah, “seed of blessing.” Botanically Nigella sativa.

In the kitchen

It scatters over naan and flatbreads, tempers vegetables and dals, and is one of the five seeds of panch phoron. Bloom it briefly in hot oil to soften its edge, or bake it onto bread for its speckle and bite.

What we know about the claims

Nigella’s compound thymoquinone is much studied, and the seed carries a long history of folk-medicinal use — but the research is preliminary and the doses in cooking are small, so it belongs on the plate as a spice, not in the medicine cabinet. Read the “miracle seed” headlines with due caution.

Choosing and buying

Sold as whole seeds (kalonji) in every South Asian grocer (UK and US); they keep well in a jar. Buy whole, not ground.
