Rub the mixture through a sieve.
Serve
Serve with boiled rice and cream on the side, if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the stock into a smooth, body-rich soup as it cooks.
- Curry powder
- Provides the main spiced, aromatic flavour of the soup.
- Butter
- Carries the frying of the vegetables and ham and adds rich flavour.
- Apples
- Add natural sweetness and a mild acidity that balances the curry spices.
- Onions
- Soften and build a sweet, savoury base for the soup.
The step that matters
Rub the mixture through a sieve. Pressing the cooked solids through a sieve breaks them down so the soup becomes smooth; skipping or rushing this leaves the texture coarse and lumpy.
Flavor stand-ins for the apple
How well each one fits the dish's main ingredients (ham, sugar, chicken, onion, butter, flour, carrot):
- Coconutabout as good a flavor fit
- Grapeabout as good a flavor fit
- Applethe original
- Lemonabout as good a flavor fit
Fit is the average pairing score against ham, sugar, chicken, onion, butter, flour, carrot. 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).
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
