Sweet potato souffle

A soufflé is a baked egg dish originating in France in the early 18th century. Combined with various other ingredients, it can be served as a savoury main dish or sweetened as a dessert. The word soufflé is the past participle of the French verb souffler, which means to blow, breathe, inflate or puff. The earliest mention of soufflé is attributed to the French master cook, Vincent La Chapelle, in the early eighteenth century. The development and popularisation of the soufflé is usually traced to the French chef Marie-Antoine Carême in the early nineteenth century.
