This topping will transform a number of soups into a very special affair. It is good on split pea soup, or split pea soup mixed half and half with canned green turtle soup, Boston black bean soup, lentil or tomato soup. This amount of topping will garnish six bowls of soup.
Combine egg yolk and cheese and mix to a smooth paste. Fold in the whipped cream. Swirl on top of soup in ovenproof bowls and brown quickly under the broiler. A tablespoon of Madeira or sherry added to the soup will make it even more festive.
