Parfait is either of two types of dessert. In France, where the dish originated, parfait is made by boiling cream, egg, sugar and syrup to create a custard-like puree. The American version consists of layers differentiated by the inclusion of such ingredients as granola, nuts, yogurt and liqueurs, topped off with fruits or whipped cream. The oldest known recipe dates back to 1894.
Either type is typically served in tall glassware together with a long spoon known as parfait spoon. The classical parfait glass is stemware, with a short stem and a tall slender bowl, often tapered towards the bottom, also used for serving milkshakes.
