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 cucumbers very thin, or quarter and cut them into half‑inch lengths, removing the seeds.
Soak the cucumbers in vinegar and sprinkle with salt for 30 minutes.
Drain and press the cucumbers dry with a soft cloth.
Dredge the cucumbers in flour.
Cook and finish the sauce
Melt butter in a saucepan over medium heat.
Add the cucumbers to the melted butter.
Cook gently for 10 minutes without browning them.
Gradually add veal stock until the cucumbers are nearly covered.
Once boiling, skim off any fat, then season with salt and white pepper as needed.
When the cucumbers are tender, stir in 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
- Form the main body of the dish, becoming tender as they simmer in the sauce.
- Flour
- Thickens the butter and stock into a smooth sauce that coats the cucumbers.
- Butter
- Carries the cooking of the cucumbers and adds richness to the sauce.
- Veal stock
- Provides the liquid and savory body of the sauce.
- Egg yolks
- Enrich and thicken the finished sauce, giving it a smooth, velvety texture.
The step that matters
Thickening the sauce with egg yolks. Egg yolks thicken through gentle heat; if the sauce boils after they go in, they can scramble and curdle, so the sauce should be kept warm, not boiling, when they are stirred in.
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.
