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

What each ingredient does

Eggs
Set into a delicate structure as they cook, forming the body of the dish.
Butter
Provides fat for frying and, heated further, develops nutty, toasted flavor in the sauce.
Vinegar
Adds acidity that sharpens the rich, nutty butter and cuts through the fat.

The step that matters

Heating the 2 ounces of butter to lemon color. Butter browns quickly once its water has evaporated, so heating it only to a pale lemon color gives nutty flavor without burning. Past that point the milk solids turn bitter and dark, spoiling the sauce.

Swap the white pepper

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

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

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