Ravigote Butter
Ingredients
Directions
Blanch the herbs
Bring a small saucepan of salted water to a boil.
Add the chervil, parsley, tarragon, pimpernel, chives, and shallots.
Boil for 2 minutes, then drain and cool in cold water.

Make the butter
Pound the herbs in a mortar until smooth.
Mix the herb puree with the half-melted butter until well combined.
Pass the mixture through a fine sieve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chervil
- Adds a delicate, fresh anise-like aroma that defines the butter's flavour.
- Parsley
- Contributes bright green colour and a fresh, mild herbal flavour.
- Tarragon
- Provides the characteristic aromatic, slightly anise-like flavour of ravigote.
- Chives
- Adds a mild onion-like freshness and aroma.
- Butter
- Carries the herb flavour and gives the finished butter a rich, smooth texture.
The step that matters
Press the herbs dry. Blanched herbs hold a lot of water. Leftover moisture would dilute the butter and can make it split or spoil faster, so the herbs should be squeezed thoroughly before pounding.
Swap the parsley
How well each one fits the dish's main ingredients (chervil, tarragon, chive, shallot, butter):
- Capersfits better
- Parsleythe original
