Place whipping cream and milk in heavy 2-quart saucepan. Cook over medium-high heat 2-3 minutes, stirring occasionally, until mixture just comes to a boil. Immediately remove from heat. Add chocolate; whisk until melted and smooth.

Step 2

Whisk yolks in bowl just to blend. Gradually whisk warm chocolate mixture into beaten yolks. Return chocolate mixture to same saucepan. Cook over medium heat 8-10 minutes, stirring constantly, until mixture thickens and just begins to bubble. Do not boil.
