Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Butter Salad Dressing
Ingredients
Directions
Make the base
In a deep saucepan, boil the vinegar and butter together.
Beat the egg yolks until light.
Gradually pour in the boiling vinegar and butter while continuing to beat.
Cook and thicken
Place the mixture over low heat and beat until it begins to thicken.
Slowly pour in the cream while continuing to beat until the mixture resembles cream or boiled custard.
Do not let it boil, or it will curdle.
Season and chill
Add salt and pepper.
Beat the mixture in a bowl set over ice water until cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify the butter and vinegar and thicken the dressing as they cook.
- Butter
- Adds richness and fat, giving the dressing a smooth, creamy body.
- Vinegar
- Provides sharp acidity that balances the richness of the butter and yolks.
- Thin sweet cream
- Adds moisture and mild richness, loosening the thickened mixture.
The step that matters
Keep the mixture off the boil. Egg yolks coagulate and curdle when overheated, so the dressing must thicken gently over low heat and stay below boiling.
Swap the white pepper
How well each one fits the dish's main ingredients (butter, egg, vinegar, pepper, cream):
- Tarragonfits better
- Parsleyfits better
- Nutmegfits better
- White pepperthe original
Fit is the average pairing score against butter, egg, vinegar, pepper, cream. Candidates are from the same food group and used in at least 100 recipes.
