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 butter and thicken gently as they heat, giving the sauce its body.
Melted butter
Provides the fat that gives the sauce its rich, smooth texture.
Double cream
Adds moisture and richness, making the sauce lighter and silkier when whipped in.
Lemon juice
Adds acidity that brightens the rich butter and yolks.

The step that matters

Whisk over gentle heat without boiling. Egg yolks thicken through gentle heat, but if they get too hot they scramble and curdle, and the emulsion breaks. Indirect heat from the water bath and constant whisking keep the sauce smooth.

Swap the capers

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

  1. Parsleyfits better
  2. Nutmegfits better
  3. Tarragonfits better
  4. Capersthe original

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