Parsley and Butter Sauce
Ingredients
Directions
Prepare the parsley
Soak the parsley in water for 30 minutes, then wash it well in two more waters to remove grit.
Boil the washed parsley in clean water with a pinch of salt until tender.
Remove the parsley from the water, scrape the leaves off the stalks, and chop the leaves finely.
Make the sauce
Mix the chopped parsley into the melted butter in a saucepan.
Serve the sauce in a sauce-tureen or boat.

What each ingredient does
- Parsley
- Adds fresh, green herbal flavour and aroma that brightens the rich butter.
- Butter
- Provides fat that carries flavour and gives the sauce a smooth, rich texture.
The step that matters
Boil the parsley only until tender. Prolonged boiling breaks down the chlorophyll in parsley, dulling its green colour and washing out some of its fresh flavour, so the parsley should be removed once it is tender.
