What each ingredient does
- Parsley
- Supplies the fresh, herbal flavour and green colour that define the sauce.
- Butter
- Carries the flavour and gives the sauce a smooth, rich, fatty texture as it melts.
The step that matters
Boil the parsley only until tender. Prolonged boiling breaks down the green chlorophyll pigment, turning the parsley dull olive and dulling the sauce's fresh flavour.
