Creme Brulee (pronounced "krem broo-LAY") is a classic French dessert consisting of a custard topped with caramelized sugar.
The custard for creme brulee is traditionally made with cream, egg yolks and sugar, and flavored with vanilla.
Caramelizing the sugar on top of the creme brulee is usually done with a small butane torch. Creme brulee means "burnt cream" in French, as the caramelized sugar on top of the custard is characteristic of creme brulee.
