Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg yolks
Emulsify with the oil and vinegar to give the dressing a thick, creamy body.
Salad oil
Coats the lettuce leaves, carrying flavour and adding a smooth richness.
Vinegar
Adds acidity that sharpens the dressing and balances the sugar.
White sugar
Softens the sharpness of the vinegar and rounds out the dressing's flavour.
