This traditional egg custard dessert consists of egg yolks, cream, sugar, and vanilla, with a hard, burnt, toffee crust. The combination is cooked, transferred into ramekins, poached in a bain-marie, then well chilled. The chilled custard is typically set in wide, flat dishes, and is then topped with brown sugar which is either caramelized under a broiler or with a blowtorch.
The origins of the dish are quite unclear, and England, Spain, and France all claim to have invented it. However, most food historians agree that custards were popular as far back as the Middle Ages, and recipes for custards circulated throughout Europe for centuries.
The Spanish claim to have invented it in the 18th century under the name crema Catalana, while the English claim it was their invention from the 17th century, when it was known as burnt cream. At the end of the 19th century, the French term crème brûlée became popular, putting the dessert on the map from Paris to New York City.
