Why it works: Cucumber and rice match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 734 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Vegetable Mullagatawny
2 quartsIngredients
Directions
Prepare the vegetables
Melt the butter in a large stewpan until it is about to brown.
Add the sliced onions, vegetable marrow, cucumbers, and acid apples.
Stir the mixture often.
Cook over gentle heat until the vegetables are tender.
Mix in the curry powder and salt.
Stew for an additional 20 to 30 minutes.
Gradually pour in enough boiling water to just cover the vegetables.
Strain and finish
Press the mixture through a fine sieve with a wooden spoon when it is nearly a pulp.
Heat the strained mixture in a clean stewpan.
Add enough liquid to make 2 quarts.
Adjust seasoning with salt, cayenne, or acid as needed.
If butter appears on the surface, skim it off.
Stir in arrow‑root mixed with cold broth to absorb the butter.
Serve hot.
Serve with rice if desired, though the soup is thick enough on its own.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and carries the curry flavour into the soup.
- Onions
- Break down while stewing to build body and a sweet, savoury base.
- Vegetable marrow
- Softens into the purée, adding bulk and a mild, tender texture.
- Cucumbers
- Soften and add moisture and a fresh, mild vegetable flavour.
- Acid apples
- Add acidity and fruitiness that balance the curry and help thicken the purée.
- Curry powder
- Provides the main spice aroma and flavour of the soup.
The step that matters
Pressing the mixture through the sieve when nearly pulped. If the vegetables are not soft enough, the purée stays grainy and thin. Pressing while they are nearly pulp lets the pectin and starch release for a smooth, thick texture.

Fit is the average pairing score against butter, onion, cucumber, pepper, rice. Candidates are from the same food group and used in at least 100 recipes.
