While searching for something else, I came across this recipe on a message board.
"Oyster Artichoke Soup" from D.H. Holmes in downtown New Orleans.
1/2 cup butter
2 bunches green onions, chopped
3 ribs celery, chopped
3 cloves garlic, pressed
1-3/4 pounds fresh cut artichoke hearts, or
3 9-oz. packages frozen artichoke hearts, defrosted and quartered
OR 2 (14 oz) cans artichoke hearts, washed, drained, and quartered (save canned hearts as a last resort)
3 tablespoons flour
1 to 1-1/2 quarts homemade chicken stock
Cayenne to taste
1 teaspoon salt
1 tablespoon Worcestershire sauce
1/2 teaspoon fresh thyme
1 quart oysters, drained and chopped (reserve liquor)
1/3 cup sherry
1 cup half-and-half
1 cup milk
In a heavy 4-quart pot melt the butter over medium heat. Add the green onion, celery, and garlic
and saute' until soft. Add the artichokes. Sprinkle the mixture with the flour and stir to coat
the vegetables well, but do not let the flour brown. Gradually add the stock, stirring constantly.
Add the cayenne, salt, Worcestershire sauce, and thyme. Simmer the mixture, covered, for 1 hour.
Add the oysters, oyster liquor, and sherry and simmer for 10 minutes. Do not allow the soup to boil.
Stir in the cream and milk. Cool and refrigerate for at least 8 hours. Before serving, heat the soup
slowly over low heat. Serves 8 bowls or 16 cups.
