In a medium-sized saucepan over medium heat stir together the cranberries, sugar, and water until the sugar has dissolved and the cranberries have popped open. Remove from heat and set aside to cool completely.

Drop the clementine peel in a large mason jar. Pour in the cooled cranberry mixture, and then the vodka. Tightly screw on the lid and give a shake. Set the jar aside at room temperature anywhere from 3 days to a month. Shake the jar everyday.

Strain the cranberry-infused vodka into another large mason jar, and refrigerate. Now you're good to go! Add it to your favorite cocktail!
