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

What each ingredient does

Eggs
Thicken the dressing and bind it into a creamy emulsion as they cook.
Flour
Stabilizes the emulsion and adds body so the dressing thickens smoothly.
Mustard
Adds sharp flavor and helps emulsify the oil and milk.
Vinegar
Provides acidity that brightens the dressing and balances the richness.
Oil
Adds fat for a rich mouthfeel and smooth texture.

The step that matters

Heat in a double boiler until creamy. Egg proteins set gradually as they warm. Gentle, indirect heat lets the dressing thicken evenly; direct high heat can scramble the eggs and make the dressing grainy.

Swap the mustard

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

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

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