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

What each ingredient does

Eggs
Provide the main body of the dish, which the sauce coats and flavours.
Sugar
Browning in the pan adds caramel sweetness and colour to the sauce.
Flour
Thickens the liquid into a smooth sauce that clings to the eggs.
Vinegar
Adds acidity that sharpens the sauce and balances the sweetness.
Prepared mustard
Contributes sharp, pungent flavour that defines the sauce.
Cream
Adds fat and richness, softening the sauce's sharpness and adding body.

The step that matters

Stir the flour mixture into the browned sugar. Flour thickens only when its starch is hydrated and heated, so the mixture should be added smoothly and stirred while the sauce simmers. Adding it in lumps or without stirring can leave clumps that prevent an even, smooth sauce.

Swap the clove

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

  1. Cinnamonfits better
  2. Tarragonfits better
  3. Capersfits better
  4. Clovethe original

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