What each ingredient does
- Parsley
- Provides the main fresh, herbal flavor and the green color of the sauce.
- Butter
- Carries the flavor and gives the sauce a smooth, rich texture.
The step that matters
Boiling the parsley briefly. Parsley's green color comes from chlorophyll, which breaks down into a dull olive shade with prolonged heat. A short boil in salted water helps the leaves stay bright green, so boil only briefly and move on.
