Ingredients

2 dozen large oysters, shucked, with all their liquor and the
deeper halves of their shells reserved and scrubbed
1 bottle of clam broth
2 sticks butter, cubed
1 cup flour
1 cup minced onions
3 tablespoons anchovy paste
1 tablespoon chopped garlic
1 1/2 pounds fresh watercress, washed, patted dry, trimmed, and finely chopped
1 1/2 pounds fresh spinach, washed, patted dry, trimmed and finely chopped
1/2 cup Herbsaint

Rock salt
1/2 cup grated Parmesan cheese

Directions

Preheat the oven to 400
degrees F.

Drain the oysters and liquid through a fine mesh strainer. You should have 3 cups of
oyster liquor, if not add enough clam broth to make up for the difference. In a large
saute pan, melt the butter over medium heat. Stir in the flour and cook for 4 minutes.
Stir in the onions and cook for 2 minutes. Stir in the anchovy paste, garlic, watercress,
and spinach. Season with salt and pepper. Cook for 1 minute. Stir in the oyster liquor and
bring the liquid up to a boil. Reduce to a simmer and continue to cook for 8 to 10 minutes
or until the sauce is thick. Remove from the heat and stir in the Herbsaint. Reseason with
salt and pepper if needed. Spread the rock salt evenly over a large sheet pan. Arrange the
oyster shells on the baking sheet. Place the oysters back in their shells. Season the
oysters with salt and pepper. Place a heaping spoonful of the filling on top of each
oyster. Using the back of the spoon, gingerly pat the filling into the shell. Sprinkle the
top of the oyster with the grated cheese. Place the baking sheet in the oven and cook for

about 15 minutes or until the sauce is golden brown and the oysters have curled. Remove
from the oven and serve on a large platter. Serve the oysters with fish forks and fresh
lemons.
