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

What each ingredient does

Eggs
Thicken the dressing as they set when gently heated, giving body to the sauce.
Flour
Thickens the liquid by absorbing water and swelling as it heats.
Vinegar
Adds acidity that gives the dressing its sharp, tangy flavor.
Sugar
Balances the acidity with sweetness.
Olive oil or butter
Adds richness and fat, giving the dressing a smoother mouthfeel.

The step that matters

Adding the oil or butter. Fat added too quickly to a hot egg mixture can fail to emulsify and may curdle or separate. Adding olive oil slowly while stirring lets it disperse evenly, and adding butter after thickening keeps the dressing smooth.

Swap the mustard

How well each one fits the dish's main ingredients (flour, pepper, sugar, egg, vinegar, olive):

  1. Capsicumfits better
  2. Mustardthe original
  3. Cucumberfits about as well
  4. Shallotfits about as well

Fit is the average pairing score against flour, pepper, sugar, egg, vinegar, olive. Candidates are from the same food group and used in at least 100 recipes.
