Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tamarind
- Provides the sour acidity that defines the soup's tangy flavour.
- Dry chillies
- Supply heat and a deeper, sharper pungency to the soup.
- Cumin seeds
- Add warm, earthy aroma when their flavour is released in the spice mix.
- Ghee
- Adds richness and a rounded, buttery aroma that carries the spices.
- Coconut milk (in the method)
- Adds fat and body, softening the sourness and heat for a smoother soup.
The step that matters
Reducing the tamarind mixture to half. Reduction concentrates the sourness, heat and salt together. Reducing too far makes the soup overly sharp, salty or intense, while stopping early leaves it thin and flat.
