Crème Brûlée is a classic French dessert made of cream, egg yolks and sugar finished with a thin lid of crisp roasted sugar.
The Crème Brûlées should not start to bubble / boil when baking. Make sure you can turn down the heat if this occurs - because your oven may be hotter than the set temperature. It must have a ""smooth"" surface. Instead of using a gas burner, you can place the Crème Brûlées in an ice-cold water bath - preferably with ice cubes. Sprinkle with sugar and grill them at the top of the oven until the sugar is melted and golden - keep an eye out, because colour can change quickly. Take them out and serve immediately.
