Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify and thicken the dressing as they cook gently, giving it a creamy body.
- Vinegar
- Adds acidity that sharpens the dressing and balances the richness of the yolks and butter.
- Butter
- Adds fat and richness, softening the sharpness of the vinegar in the dressing.
- Cream
- Adds moisture and richness, loosening the dressing and making it smooth.
- Sour apple
- Adds crisp texture and tart flavour that contrasts with the dressing.
- Walnuts
- Add crunch and a nutty flavour to the salad.
The step that matters
Heating the egg yolk mixture. Egg yolks thicken when heated gently but can scramble if they overheat. Heat only until the mixture just comes to a boil, then remove it from the heat, and let it cool before adding the cream so the dressing stays smooth.
