Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Black pepper
- Provides the sharp, pungent heat that defines the dish.
- Red pulse
- Adds body and thickness to the paste as it is ground.
- Tamarind pulp
- Supplies the sour, acidic flavour of the broth.
- Ghee
- Carries the aroma of the spices and adds richness when frying.
- Fenugreek seeds
- Adds a bittersweet, aromatic note when fried in ghee.
The step that matters
Bringing the mixture to a boil two or three times. Repeated boiling extracts flavour from the tamarind and paste and fully blends them. Boiling too hard or too long can dull the aroma of the pepper and spices, so watch the pot closely.
Swap the apple
The recipe marks apple as optional. How well each one fits the dish's main ingredients (pepper, ghee, tamarind, mustard, cumin, fenugreek, lime):
- Mangofits better
- Coconutfits better
- Lemonfits better
- Applethe original
Fit is the average pairing score against pepper, ghee, tamarind, mustard, cumin, fenugreek, lime. Candidates are from the same food group and used in at least 100 recipes.
