Soufflé Rothschild is a sweet souffle flavored with candied fruit macerated in Danzinger Goldwasser, an herbal liqueur with real gold flakes, as one of its defining ingredients. Marie-Antoine Carême created it in honor of his employer, James Mayer de Rothschild, founder of the French branch of the Rothschild family and the wealthiest man at the time, hence the name.
