Fresh cranberries and oranges make this bright mocktail a refreshing break from your standard alcoholic drink. Warm cinnamon flavors and rosemary add to the depth, and the acidic vinegar flavor provides a nice punch that compensates for the lack of alcohol, making this a great choice for your next mocktail.
Combine all ingredients except the mixer in a medium sized saucepan.
Bring the mixture to a boil over medium-high, then reduce to a simmer and cook for about 20 minutes, or until all your fruit as broken down. (Give your mixture a stir periodically, and even a gentle muddling as it simmers to help this process along.)
Taste your shrub mixture and add extra sugar or vinegar depending on your tastes.
Allow cranberry orange mixture to cool completely. Then, using a fine mesh strainer, strain the mix into a large glass jar.
Discard the cinnamon stick and rosemary sprigs and reserve the cooked cranberries and oranges in a separate container for another use, or use to garnish in your mocktail.
Prepare your mocktail by filling your cup halfway with ice, adding about 2 tablespoons of the shrub, and topping the rest of the glass off with seltzer, soda or carbonated water.
Store leftover shrub in an airtight jar or container for about 3-4 weeks.
