Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onion and carrot
- Soften and sweeten as they fry, building a flavour base for the sauce.
- Curry powder
- Provides the main spice aroma, bloomed briefly in hot butter to release its fragrance.
- Sour apple
- Adds tartness and body that balances the richness of the sauce.
- Tomato puree
- Adds concentrated tomato flavour, colour and acidity to the sauce.
- Espagnole sauce
- Forms the savoury, thickened base that gives the sauce its body.
The step that matters
Fry the onion and carrot until light brown. Browning the onion and carrot develops sweet, savoury flavour through caramelisation. Frying too briefly leaves a raw, flat taste, while over-browning can make the sauce bitter.
Swap the apple
How well each one fits the dish's main ingredients (onion, carrot, butter, tomato, sauce):
- Avocadofits better
- Mangofits better
- Cherryfits better
- Applethe original
Fit is the average pairing score against onion, carrot, butter, tomato, sauce. Candidates are from the same food group and used in at least 100 recipes.
