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 remove seeds, cutting into half-inch lengths.
Soak cucumbers in vinegar and sprinkle with coarse sea salt for 30 minutes.
Drain and press cucumbers dry with a soft cloth.
Flour the cucumbers well.
Cook and finish the sauce
Melt butter in a saucepan over medium heat until it begins to boil.
Add cucumbers and gently shake for 10 minutes without browning them.
Gradually pour in enough strong pale veal stock to nearly cover the cucumbers.
Once boiling, skim off any fat.
Add salt and white pepper to taste.
When cucumbers are tender, stir in minced parsley.
Thicken the sauce with egg yolks.

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 salad, becoming tender while cooking in the sauce.
- Butter
- Adds richness and fat, carrying flavour while the cucumbers cook gently.
- Egg yolks
- Thicken the sauce as they set gently with heat, giving it body and richness.
- Strong pale veal stock or gravy
- Provides the savoury liquid base that forms the sauce.
- Vinegar
- Adds acidity that brightens the cucumbers and sharpens the finished sauce.
The step that matters
Thicken the sauce with egg yolks. Egg yolks set when heated, but if the sauce boils after they are added they can scramble and turn grainy. Keep the heat low and stir steadily.
