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 them, removing the seeds and cutting into half‑inch lengths.
Soak the cucumbers in vinegar and sprinkle with salt for 30 minutes.
Press the cucumbers dry with a soft cloth and coat them with flour.
Cook and finish the sauce
Melt butter in a saucepan over medium heat until it begins to boil.
Add the cucumbers and gently shake for 10 minutes, avoiding any color change.
Gradually pour in enough veal stock to nearly cover the cucumbers and bring to a boil.
Skim off any fat, then add salt and white pepper to taste.
Once the cucumbers are tender, stir in the minced parsley.
Thicken the sauce with the yolks of 2 or 3 eggs.

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
- Main vegetable, cooked until tender and soft in the sauce.
- Flour
- Coats the cucumbers and thickens the butter and stock into a sauce.
- Butter
- Fat for gently cooking the cucumbers and adding richness to the sauce.
- Veal stock
- Liquid base that forms the savory body of the sauce.
- Egg yolks
- Enrich and thicken the sauce at the end of cooking.
The step that matters
Thicken the sauce with the yolks. Egg yolks thicken when gently heated but can curdle or scramble if the sauce boils after they are added, so heat should stay low and the sauce should not be allowed to boil once the yolks go 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.
