Procedures

1. 1

   Combine the milk, cream, vanilla bean, cinnamon stick, and ground cinnamon in a large saucepan over medium-low heat. Cook, stirring constantly, until just under a boil (you will see bubbles along the edges of the pot and steam rising from the surface). Remove from heat.

2. 2

   In a medium bowl, whisk the egg yolks and the sugar until lightened. Slowly add a few tablespoons (no more than a 1/4 cup total) of the hot milk mixture into the yolks, whisking constantly, then add the yolks back to the rest of the milk, whisking constantly.
