Dice up 2 cups of cooked turkey meat, white meat preferred. Make a roux by melting the butter in the top of a double boiler. Stir in the flour, salt and cayenne until smooth. Gradually add the half-and-half to the roux and continue stirring until all is blended and starting to thicken.
Add the sherry to the egg yolks and stir until blended, then temper the egg mixture by adding a small amount of the sauce to the eggs then adding the egg mixture back into the sauce. Continue stirring until the sauce thickens.
Then add the diced turkey meat. Allow the turkey meat to warm, approximately 5 minutes. Serve over the cooked white rice.
