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

What each ingredient does

Fresh butter
Provides the fat base that carries the flavours and sets firm when chilled.
Hard boiled egg yolk
Adds richness and body, helping the mixture bind into a smooth paste.
Anchovy
Adds a salty, savoury depth that rounds out the herbs.
Parsley
Contributes fresh, green aroma and colour to the butter.
Capers
Add a sharp, briny acidity that cuts through the richness of the butter.
Salad oil
Keeps the butter softer and easier to spread when chilled.

The step that matters

Strain the blanched herbs very dry. Excess water left in the herbs would dilute the butter fat, making the mixture loose and less able to set firm when chilled.

Swap the fennel

How well each one fits the dish's main ingredients (butter, anchovy, egg, parsley, shallot, capers, spinach):

  1. Tarragonfits better
  2. Thymefits better
  3. Nutmegfits better
  4. Fennelthe original

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