Why it works: Cucumber and parsley match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 1,564 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓
Cucumbers a LA Poulette
Ingredients
Directions
Prepare the cucumbers
Peel and slice the cucumbers very thin, or quarter and remove seeds, cutting into half-inch lengths.
Soak cucumbers in vinegar and sprinkle with salt for 30 minutes.
Drain and press dry with a soft cloth.
Cook and finish the sauce
In a saucepan, melt butter over medium heat, then add the cucumbers and cook for 10 minutes without browning.
Gradually add veal stock until cucumbers are nearly covered, then bring to a boil.
Skim off any fat, season with salt and white pepper, and cook until cucumbers are tender.
Stir in minced parsley and thicken the sauce with egg yolks.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Make up the main body of the dish and soften into tender pieces during cooking.
- Butter
- Adds richness and carries flavour as the cucumbers cook gently in the pan.
- Veal stock
- Provides the liquid that cooks the cucumbers and forms the base of the sauce.
- Egg yolks
- Thicken the sauce and give it a smooth, rich texture when gently heated.
- Flour
- Thickens the sauce with starch, giving body to the liquid.
The step that matters
Stir in the egg yolks. Egg yolks thicken through gentle heat and can scramble if the sauce boils. Remove the pan from direct heat before whisking them in, and keep the sauce below a simmer.
Swap the white pepper
How well each one fits the dish's main ingredients (cucumber, vinegar, flour, butter, veal, parsley, egg):
- Tarragonfits better
- Capersfits better
- Dillfits better
- White pepperthe original
Fit is the average pairing score against cucumber, vinegar, flour, butter, veal, parsley, egg. Candidates are from the same food group and used in at least 100 recipes.
