- Not related to: Cumin or fennel (though they’re often confused)
- Native regions: South Asia, Middle East, and parts of Eastern Europe

Flavor Profile: Bold, Bitter, and Beautiful
Kalonji isn’t sweet. It’s not savory either. Think of it more like the spice world’s indie rock star: intense, complex, and totally unforgettable.
- Taste: Slightly bitter, nutty, with a hint of oregano and pepper
- Aroma: Earthy, musky, and slightly floral
- Mouthfeel: Crisp bite when toasted, chewy when raw
