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

What each ingredient does

Grated horseradish root
Provides the sharp, pungent heat that defines the sauce.
Egg yolks
Thicken the broth as they heat, giving the sauce a smooth, rich body.
Broth
Forms the liquid base that carries the horseradish flavor and is thickened into the sauce.
Tarragon vinegar
Adds acidity that brightens the sauce and balances the richness of the yolks.

The step that matters

Thicken the broth over low heat with the egg yolk mixture. Egg yolks set when heated, but at high heat or too quickly they can scramble and curdle. Gentle low heat and steady stirring keep the sauce smooth and thickened.

Swap the nutmeg

How well each one fits the dish's main ingredients (horseradish, egg, tarragon, vinegar, pepper):

  1. Dillfits better
  2. Parsleyfits better
  3. Capersfits better
  4. Nutmegthe original

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