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

What each ingredient does

Butter
Provides fat and a smooth, rich body that carries the herb flavour.
Hard-boiled egg yolks
Add richness and a creamy texture that helps bind the pounded mixture.
Anchovies
Add savoury depth and salt that rounds out the herbs.
Capers
Add a sharp, briny acidity that brightens the butter.

The step that matters

Press the herbs to extract all moisture. Leftover water from the blanched herbs can make the butter watery and cause it to separate, so the herbs should be squeezed dry before pounding.

Swap the spinach
