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):
- Tarragonfits better
- Thymefits better
- Nutmegfits better
- 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.
