1. Combine the milk, cream, and cinnamon sticks in a small saucepan, and bring to a boil over medium-high heat. Remove from the heat, and allow to steep for 30 minutes, until flavors are infused.

2. Fill a large bowl with ice and water; set aside. In a medium bowl, whisk egg yolks and sugar until lightened in color, about 2 minutes. Return the milk mixture to medium heat, and bring to a simmer; reduce the heat to low. Whisk about 1/2 cup of the milk mixture into the egg-yolk mixture, and return it to the saucepan. Cook until the mixture thickens enough to coat the back of a wooden spoon.

3. Strain the creme anglaise through a fine sieve into a bowl set in the ice bath, discarding the cinnamon sticks. Store in an airtight container in the refrigerator for up to 3 days.
