Ingredients (for 4 people)

  • 1.5 kg mussels
  • 1/2 onion
  • 3 celery stalks
  • Chopped parsley
  • 1/2 cup Orval (approx. 150 ml)
  • 1 tablespoon roux
  • 1 tablespoon cream
  • 1 egg yolk
  • Cognac
  • A few chervil leaves

Preparation Steps

1. Preparing the Mussels

Rinse and debeard the mussels. Place them in a pot.

2. Cooking the Vegetables

Add the finely chopped onion, celery, butter, Orval, a pinch of Guérande salt, and a little pepper. Heat on high for 4 minutes. Perform a half-rotation of the mussels in the pot with a quick motion.

3. Cooking the Mussels

Cook for another 3 minutes and perform another half-rotation to bring out the vegetables. Add the chopped parsley.

4. Extracting the Juice

Strain the juice and vegetables into a saucepan and keep only the volume of one cup.

5. Binding the Sauce

Add the shelled mussels, simmer with the roux, and add the Cognac and cream. Let it reduce slightly, then thicken with the egg yolk off the heat (or with a mousseline based on Orval).

6. Plating and Serving

Plate in a deep dish. Garnish as desired (e.g., with watercress or langoustine) and sprinkle with chervil leaves. Serve hot.
