Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Prawns
- Form the main protein and the body of the dish.
- Butter
- Carries the curry spices and adds richness and a rounded mouthfeel.
- Onion
- Browns in the butter to add sweetness and savory depth to the base.
- Spinach
- Adds moisture and a smooth, thickened texture when passed through a sieve.
The step that matters
Browning the minced onion. Onion that is pale or only softened lacks the sweet, deep base the curry needs. Browning slowly in butter lets its sugars caramelize, and the curry powder added later tastes flatter over an underdone base.
Swap the spinach
How well each one fits the dish's main ingredients (butter, onion, pepper, bread):
- Potatofits better
- Capsicumfits better
- Leekfits better
- Spinachthe original
Fit is the average pairing score against butter, onion, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
