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 ↓
Good Vegetable Mullagatawny
2 quartsIngredients
Directions
Make the base
In a large saucepan, melt the butter until it is about to brown.
Add the sliced onions, vegetable marrow, cucumbers, and acid apples.
Stir often and cook over low heat until the vegetables are tender.
Mix in the curry powder and salt, and let the vegetables stew for 20 to 30 minutes.
Gradually add enough boiling water to just cover the vegetables.
Strain and finish
When the mixture is nearly a pulp, press it through a fine sieve with a wooden spoon.
Heat the strained mixture in a clean saucepan, adding enough liquid to make 2 quarts.
Adjust seasoning with salt, cayenne, or acid as needed, and serve hot.
If butter appears on the surface, skim it off or stir in the arrowroot mixture to absorb it.
Serve with rice if desired, though the soup is thick enough to stand alone.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and a nutty flavour as it is heated close to browning.
- Vegetable marrow
- Breaks down into the bulk of the soup, giving body and a mild sweetness.
- Cucumbers
- Soften when stewed, contributing moisture and a light, fresh body to the soup.
- Acid apples
- Add tartness and natural pectin that help the soup thicken as it cooks down.
- Curry powder
- Supplies the warm, aromatic spice profile that defines the soup.
The step that matters
Stewing the vegetables gently until they collapse. Cooking over low heat with frequent stirring lets the vegetables soften and release water without scorching on the pan base. Curry powder and butter can burn at high heat, which would leave a bitter taste in the finished soup.
Swap the arrowroot
The recipe marks arrowroot as optional. How well each one fits the dish's main ingredients (butter, onion, cucumber, apple, rice, pepper):
- Capsicumfits better
- Potatofits better
- Chivefits better
- Arrowrootthe original
Fit is the average pairing score against butter, onion, cucumber, apple, rice, pepper. Candidates are from the same food group and used in at least 100 recipes.
