Open the oysters, discard the first water and place on an oven dish.
Wait for the oysters to produce their second water. Open the mussels in a saucepan with the celery and bay leaf.
Sweat the chopped shallots with the pommeau in a saucepan. Reduce the mixture until almost dry. Make the mussel velouté, then bind it with a beurre manié.
Add the velouté to the Pommeau reduction, and reduce for a few more minutes. Add the fresh cream.
Remove the second layer of water from the oysters. Cover them with the mixture and bake in the oven (220°) for 15 minutes.
Arrange on a plate lined with coarse salt to keep the oysters in balance.
It’s ready!
A beurre manié is a base for binding sauces. It's a mixture of equal parts butter and flour added to the liquid to bind it together and make the sauce... without the risk of lumps as when flour is added directly.
