6. One 12-ounce can evaporated milk
7. 16 ounces light rum
8. 1/4 cup pure vanilla extract
9. 3 large egg yolks (optional)

1. In a medium saucepan, combine the water with the lime zest and 1 cinnamon stick and simmer over moderate heat for 15 minutes. Strain into a large heatproof bowl and refrigerate until chilled, at least 1 hour.
