So here is my recipe for Blueberry Balsamic Sauce. Sweet enough to be heavenly on vanilla ice cream, pound cake, or crepes. Savory enough to go along with roasted chicken or pork, as well as silly easy to make:
You will need:
1 cup balsamic vinegar
1/2c cup sugar
1 pint blueberries
1 cinnamon stick
Bring the sugar and vinegar to a boil. Continue to boil for about 3 minutes. Add the blueberries and cinnamon stick. Return to a boil and cook for about 5 minutes. The sauce will have thicken and turn a deep purple. Serve warm or at room temperature.
