Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Coriander seeds
- Adds a citrusy, warm aroma that forms the base of the blend.
- Cumin seeds
- Contributes earthy, warm aroma that deepens when roasted.
- Turmeric
- Gives the powder its yellow colour and a mild, earthy bitterness.
- Black pepper
- Adds sharp, pungent heat that rounds out the blend.
- Dried chillies
- Provides heat and a pleasant pungency to the powder.
- Cinnamon
- Adds sweet, woody aroma that gives warmth to the blend.
The step that matters
Roast the spices until fragrant. Roasting releases volatile aromatic compounds in whole spices, so the blend tastes fuller. Under-roasting leaves it flat, while over-roasting turns spices bitter and can scorch them.
