Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Forms the rich, fatty base that carries the other flavors and gives the sauce body.
- Parsley
- Adds fresh, herbal aroma and a green flavor to the butter.
- Lemon juice
- Adds acidity that brightens the rich butter and balances its fat.
The step that matters
Boiling the sauce briefly. Once lemon juice is mixed into hot melted butter, the mixture can separate if it boils too long or too hard. Keep the heat controlled and watch closely so the sauce stays smooth and emulsified.
