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

What each ingredient does

Egg yolks
Emulsify with the mustard and oil-free base to give the sauce a thick, creamy body.
Mustard
Adds sharp heat and helps bind the sauce while balancing the richness of the yolks.
Grated onions
Contribute pungent flavor and moisture, giving the sauce its savory bite.
Vinegar
Adds acidity that brightens the sauce and softens the sharp onion flavor.

The step that matters

Strain the sauce through a sieve. Straining removes the coarse onion pulp and any lumps from the egg yolks, so the sauce turns smooth and even in texture rather than gritty or chunky.

Swap the white pepper

How well each one fits the dish's main ingredients (onion, egg, mustard, sugar, vinegar, capers, chive):

  1. Tarragonfits better
  2. Garlicfits better
  3. Dillfits better
  4. White pepperthe original

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