Creme caramel is a variant of plain custard (crème) where sugar syrup cooked to caramel stage is poured into the mold before adding the custard base. It is usually cooked in a bain-marie on a stovetop or in the oven in a water bath. It is turned and served with the caramel sauce on top, hence the alternate French names crème (caramel) renversée or crème renversée au caramel. The milk may be flavored with vanilla, cinnamon, or lemon peel.
