Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the dressing as they set with heat, giving it a smooth, creamy body.
- Butter
- Adds richness and a smooth mouthfeel to the dressing.
- Milk
- Forms the liquid base that the egg yolks thicken into a custard-like dressing.
- Cream
- Adds richness and body, softening the sharpness of the acid.
- Lemon juice
- Adds acidity that brightens the dressing and balances its richness.
- Potatoes
- Serve as the base that the dressing coats.
The step that matters
Pour the mixture over the egg yolks gradually while mixing. Adding hot liquid to raw egg yolks too quickly can scramble them. Pouring slowly while whisking mixes the yolks with the hot liquid gently, so the dressing thickens smoothly.
