Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Ingredients
Directions
Prepare
Pare the cucumbers and slice them thinly from the thick end.
Make the dressing
In a pot, add the oil and skim off all the fat.
Boil gently until the dressing is somewhat reduced without breaking the cucumbers.
Finish and serve
Stir in the egg yolks, parsley, sugar, salt, and pepper.
Bring the mixture to a boil and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Make up the bulk of the salad and take on the flavour of the dressing.
- Salad oil
- Adds fat and richness, carrying flavour and giving the dressing body.
- Vinegar
- Provides the sharp acidity that defines the dressing.
- Egg yolks
- Emulsify the oil and vinegar and thicken the dressing as they set with heat.
- Sugar
- Softens the sharpness of the vinegar, balancing the acidity.
The step that matters
Bring the mixture to a boil after adding the egg yolks. Egg yolk proteins thicken when heated but scramble and curdle if the mixture gets too hot or boils too hard. Keep the heat controlled so the dressing stays smooth.
Swap the parsley
How well each one fits the dish's main ingredients (cucumber, vinegar, pepper, egg, sugar):
- Tarragonfits better
- Dillfits better
- Cinnamonfits about as well
- Parsleythe original
Fit is the average pairing score against cucumber, vinegar, pepper, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
