Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main body and moisture of the dish as they soften in the sauce.
- Butter
- Carries the onion's flavour and helps it brown in the pan.
- Onion
- Builds a sweet, savoury base as it browns in butter.
- Curry powder
- Supplies the warm, aromatic spice flavour that defines the dish.
- Sour apple
- Adds acidity and a touch of sweetness that balances the curry spices.
- Gravy enriched with marmite
- Contributes savoury depth and salty, umami richness to the sauce.
The step that matters
Cook the tomatoes gently. Once peeled tomatoes go into the sauce, high heat can make them break down unevenly and turn the sauce watery or bitter. Gentle cooking keeps them tender and holds the sauce together.
Swap the apple
How well each one fits the dish's main ingredients (tomato, butter, onion, lemon):
- Avocadofits better
- Limefits better
- Mangofits better
