NIGELLA SEMI also called BLACK CUMIN

Nigella is an essential spice of Indian cuisine, with a spicy and peppery flavor.
The seeds come from the Nigella Sativa plant, an annual herbaceous plant native to Southwest Asia, used as a spice.
It is also called "Black Cumin", although its flavor is very different from that of cumin, or also "Onion Seed" and "Black Onion", while in Indian shops it is called "kalonji".
So if you're wondering what black cumin is, and if it differs from nigella, the answer is NO - they are the same product.
Of the nigella sativa, the seeds are used in Arab and oriental cuisine in general.
