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 set with gentle heat.
- Flour
- Thickens the mixture so the dressing becomes smooth and clings to the salad.
- Vinegar
- Provides the sharp acidity that gives the dressing its tang.
- Cream
- Adds richness and softens the sharpness once the dressing is cold.
- Sugar
- Balances the acidity of the vinegar with sweetness.
The step that matters
Thicken the vinegar mixture over low heat. Egg yolks scramble if heated too fast or too hot, which leaves lumps. Gentle, low heat while stirring lets the yolks and flour thicken the dressing smoothly.
Swap the walnut
How well each one fits the dish's main ingredients (mustard, flour, sugar, pepper, butter, egg, vinegar):
