Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Provides fat and richness, and firms as it cools so the mixture holds its shape.
- Parsley
- Supplies fresh, herbal aroma and green colour through its finely chopped leaves.
- Lemon juice
- Adds acidity that brightens and cuts the richness of the butter.
The step that matters
Mix thoroughly. Even mixing spreads the parsley, lemon juice and seasoning evenly through the butter. Uneven mixing leaves some rounds bland and others sharp or strongly flavoured.
