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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Form the main body of the soup and give it its fresh, mild flavour.
- Veal stock
- Supplies the savoury liquid that cooks the cucumbers and sets the soup's base flavour.
- Arrow-root or rice flour
- Thickens the strained liquid so the soup has body.
- Boiling cream
- Adds richness and a smooth, creamy texture.
- Egg yolks
- Enrich and thicken the soup, adding body and a silky texture.
The step that matters
Thickening with starch. Starch must be stirred into the simmering soup and then cooked to activate its thickening; adding it too little or too late leaves the soup thin or floury-tasting.
Swap the parsley
The recipe marks parsley as optional. How well each one fits the dish's main ingredients (cucumber, onion, veal, rice, cream, egg, vinegar):
- Garlicfits better
- Tarragonfits better
- Capersfits about as well
- Parsleythe original
Fit is the average pairing score against cucumber, onion, veal, rice, cream, egg, vinegar. Candidates are from the same food group and used in at least 100 recipes.
