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

What each ingredient does

Egg yolks
Pound into a smooth, rich paste that forms the body of the dish.
Butter
Adds fat and richness, binding the yolks into a spreadable paste.
Anchovy sauce
Adds savory, salty depth that gives the paste its character.
Clarified butter
Forms a seal over the tops, excluding air and helping the pots keep.

The step that matters

Pounding the yolks smooth with the anchovy sauce. If the yolks are not pounded fine and mixed evenly with the butter, the paste stays grainy and lumpy instead of smooth and spreadable. Fat from the butter coats the yolk particles, so thorough working gives an even texture.

Swap the white pepper

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

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

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