Blueberry Sauce

8-10 cup of fresh blueberries, rinsed and drained
2 cups sugar (next time I'd cut the sugar by at least half - this batch was too sweet)
2 cups water
2 cups fresh blueberries, rinsed and drained (you will add these later)
1/2 teaspoon ground cinnamon
1 1/2 teaspoons fresh lemon zest
3 Tablespoons lemon juice (bottled)

Combine the  8 - 10 cups of blueberries, sugar and water in a large stainless steel pot. Bring to a boil over medium high heat. Maintain the mixture at a steady boil for 15 minutes. Stir and mash the berries as they cook.

Add the 2 cups of blueberries and the cinnamon. Boil for 3-4 minutes. Remove from the heat and add the lemon zest and juice. 

Fill clean 1/2 pint jars, allowing 1/2 inch headspace. Process in a boiling water bath for 10 minutes. 

Yields 8 jars (1/2 pint)
