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 ↓
Cucumber Soup
Ingredients
Directions
Prepare
Pare, split, and remove seeds from the cucumbers. Sprinkle with salt and let drain for 1 hour.
Make the soup
In a deep saucepan, combine cucumbers and the white part of the onions. Cover with veal stock and stew gently for 45 to 75 minutes until tender.
Pass the mixture through a fine sieve and add more stock to reach desired soup quantity.
Stir in thickening agent (arrow-root or rice flour) until the soup reaches a good consistency.
Add boiling cream and season with salt and cayenne. Serve immediately.
Add the variation
For a variation, mix egg yolks with chili vinegar and stir in minced parsley just before serving, without boiling.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Make up the body of the soup and give it its fresh, mild flavor once cooked and sieved.
- Pale veal stock
- Cooks the cucumbers to tenderness and sets the liquid base of the soup.
- Arrow-root or rice flour
- Thickens the soup to a smooth, good consistency.
- Cream
- Adds richness and a smooth, velvety body to the finished soup.
- Egg yolks
- Add richness and body to the optional variation when mixed in without boiling.
The step that matters
Add the cream and egg yolks without boiling. Cream and egg yolks can curdle or turn grainy when they boil. Adding boiling cream and keeping the yolk variation off the heat keeps the soup smooth and silky.
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.
