In a small to medium sized pot combine the sugar and water.
Whisk until the sugar dissolves.
Add the cranberries and orange peel and cook over medium/high heat until the cranberries begin to burst (3-5 minutes).
Cook for one more minute.
Remove from heat and all too steep for 15 minutes.
Strain the syrup into an airtight storage container. Store in the refrigerator for at least 2 weeks.
Notes
You can use mandarin peel instead of orange peel. You could also use a different kind of citrus peel like lemon or grapefruit but I like the flavor or orange and mandarin best in this recipe.
Swap the granulated white sugar for brown sugar to add a slightly different flavor.
Add a small pinch of cinnamon or nutmeg to make this cranberry syrup more holiday-flavored.
