Nigella vs cumin
Nigella is sold as black cumin and is a buttercup relative rather than an Apiaceae. They share a shelf, a colour and a name across several languages, and they taste nothing alike.

What is being compared
Why these get confused
Nigella’s most common English name contains the word cumin, and it is not a cumin.
Point by point
| Aspect | Nigella | Cumin |
|---|---|---|
| The plant family | Ranunculaceae — a buttercup relative, unrelated to any other seed it shares a name with. | Apiaceae, the carrot family, alongside caraway, coriander, fennel and dill. |
| Native range | Iraq and Turkey. | Possible central Asian or Egyptian origin, per GRIN, and grown mostly in India. |
| Appearance | Matte black, angular, faceted. Scattered visibly on breads from Turkey to Bengal. | Pale brown, ridged, elongated. Almost always cooked into a dish rather than shown on it. |
| Flavour | Bitter, peppery and faintly oniony, with a herbal oregano-adjacent top note. | Warm, earthy and musky, with a sweaty depth that toasting turns nutty. |
| As a drink | Infused as a household preparation across the Middle East and South Asia. | Jeera water is made daily in Indian homes and served in place of plain water. |
| Names it collects | Black cumin, onion seed, black caraway, kalonji, habbat al-barakah — none of them accurate. | Jeera, zeera, comino, kammun. The confusion with kümmel and caraway is centuries old. |
The short answer
If a South Asian recipe says kalonji it means nigella and if it says jeera it means cumin, and substituting either way produces a dish nobody would recognise.
