1. In a bowl, combine melted butter, bread crumbs, 1/2 cup of the Parmesan
cheese, herbes de Provence, and a pinch of salt and pepper.
2. Shuck the oysters, reserving their juice. Scrub and dry bottom shells.
3. Place the onion, bay leaf, clove, and milk in a small heavy saucepan over
medium heat. When the mixture comes to a boil, remove the pan from the heat.
Reserve and keep warm.
4. Melt the 6 Tbs. butter in a medium saute pan over low heat. When the butter is
foamy, add the flour and briskly mix together to form a smooth paste. Continue to
stir over low heat for one minute. Remove from the heat and strain the milk mixture
into the paste, stirring constantly. Return the pan to low heat and fold in the
remaining 1/4 cup of Parmesan cheese, the horseradish and nutmeg. Season with
salt, pepper, and Tabasco sauce. Cook for an additional minute, then turn off the
heat.
5. Fill a large, deep saucepan with water and bring to a boil. Fill a second
saucepan or large bowl with cold water and ice cubes. In the boiling water, poach
the oysters for about one minute, or just until the edges curl. Remove with a
slotted spoon and plunge immediately into the ice water. Drain dry on paper
towels.
6. Preheat the oven to 375 degrees. Place a layer of rock salt about 1/2 inch deep
in metal baking pans. Press the shells onto the salt. Spoon a tablespoon of sauce
into each shell, then top with an oyster. Cover with another tablespoon of sauce,
and, finally, a spoonful of buttered herb breadcrumbs. Place in the preheated oven
and bake for ten minutes, or until a golden crust forms.
7. Warm six salad plates and place four oysters on each. Garnish with a sprig of
fresh rosemary. Serve immediately.
Serves six.
