Combine the sugar and water in a small saucepan over medium heat.
Break the cinnamon sticks up into smaller pieces and add then to the pan.
Stir frequently to help the sugar dissolve, then bring the liquid to a boil.
Once bubbling, reduce the heat and simmer for five to ten minutes, or until the liquid is a pale yellow and flavorful.
Remove the pan from the heat and allow the syrup to cool fully before removing the cinnamon sticks. If any small particles remain, you can strain the syrup through a fine mesh strainer.
Store your cinnamon simple syrup in a glass bottle or jar in the refrigerator for at least two weeks.
