Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Fat that carries the curry flavour and helps the onions and vegetables brown.
- Onions
- Provide savoury sweetness and body as they soften and brown in the fat.
- Apples
- Add gentle sweetness and acidity that balances the sharp curry spices.
- Curry powder
- Supplies the spiced aroma and flavour that define the soup.
- Fowl, rabbit, knuckle of veal, or cow-heel
- Gives the meat and its cooking liquid the body and richness of the soup.
The step that matters
Let the onions, apples, and carrot brown. Browning in butter caramelises the natural sugars and builds deeper flavour, but scorching turns them bitter. Keep the heat moderate and stir so the vegetables colour evenly.
Flavor stand-ins for the apple
How well each one fits the dish's main ingredients (rabbit, butter, onion, carrot, pepper):

- Mangobetter flavor fit
- Limebetter flavor fit
- Applethe original
Fit is the average pairing score against rabbit, butter, onion, carrot, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
