Dark and white chocolate crème brûlée

Ingredients
dark chocolate, 50 g, white chocolate, 50 g, sugar, 20 g, egg yolk, 1, cream, 15 g
Method
• Melt the white and dark chocolate separately, and pour the liquids into ramekins.
• Now place the ramekins into a large roasting pan. Pour enough hot water into the pan so that it comes halfway up the sides of the ramekins.
• Bake just until the crème brûlée is set. Then, remove the ramekins from water, and refrigerate.
• In a medium bowl, whisk the sugar and egg yolk until well blended.
• Add the cream, a little at a time, stirring continuously.
• Now melt this mixture to form a crispy top. Place it with the chocolate just before serving.
