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

What each ingredient does

Egg yolks
Emulsify the fats and liquids and set into a thick, creamy texture when heated.
Flour
Thickens the dressing as its starch swells and gelatinizes during cooking.
Melted butter
Adds fat for richness, smoothness and a mellow flavour.
Milk
Supplies liquid that makes the dressing smooth and pourable before it thickens.
Vinegar
Adds acidity that gives the dressing its tang and balances the richness.
Mustard
Helps stabilise the emulsion and adds a sharp, savoury bite.

The step that matters

Cook the mixture in a double boiler until it thickens. Egg yolks can curdle or scramble if overheated. A double boiler applies gentle, indirect heat, and stirring keeps the yolks evenly warmed so the mixture thickens smoothly.

Swap the white pepper

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

  1. Capersfits better
  2. Tarragonfits better
  3. Cinnamonfits better
  4. White pepperthe original

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