Stir until the butter is melted and absorbed. Stir in the garlic bechamel. Add salt and freshly ground pepper to taste. Stuff each mushroom cap with the mixture, mounding it neatly over the top. Sprinkle each with some cayenne pepper. Put stuffed mushrooms in a lightly oiled, shallow baking dish. Bake for 10 minutes or until heated through. Serve at once.

Reduce the heat and cook gently, stirring frequently, for 10 to 15 minutes. Add salt and pepper and whisk in the garlic puree. Remove from the heat. Beat the egg in a bowl.
