Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Provides the rich fat base that carries the flavours and gives the sauce its smooth body.
- Cress or parsley
- Adds fresh, green aroma and a herbal flavour to the butter.
- Lemon juice
- Adds acidity that brightens the rich butter and balances its richness.
The step that matters
Wring the herbs dry. Excess water left in the chopped cress or parsley would thin the creamed butter and make the sauce watery and loose instead of smooth and clinging. Drying the herbs keeps the butter base thick.
