Parsley and Butter
Ingredients
Directions
Prepare the parsley
Pick fresh parsley, removing any dead leaves or dirt, and leave the stalks attached.
Tie the parsley into a bundle and place it in a pot of fast boiling water.
Add the salt and boil for 6 to 10 minutes until the leaves are tender.
Drain the parsley using a sieve and chop it as finely as possible.
Finish the butter
Stir the chopped parsley into melted butter just before serving.

What each ingredient does
- Fine young parsley
- Provides the main green flavour and, once chopped, the texture of the butter.
- Butter
- Carries the parsley and gives the sauce its rich, smooth body.
The step that matters
Boil the parsley until tender. Boiling softens the leaves and mellows their bitter, raw edge, so the butter tastes of parsley rather than grass. Timing matters: boil until the leaves are tender, then drain well so excess water does not dilute the butter.
