Watermelon Cranberry Sauce

4 cups fresh cranberries
½ cup organic sugar
1 teaspoon vanilla extract
Juice from 1 lemon
Zest from 1 lemon
½ cup maple syrup
Dash cinnamon

Heat cranberries, sugar, vanilla, lemon juice and zest in a 3-quart saucepan over medium low heat until it simmers. Simmer gently, stirring occasionally, until cranberries are tender, about 15 to 20 minutes. Reduce heat to low and add the maple syrup and cinnamon to the pan. Simmer another few minutes. Remove from heat to rest for  10 minutes. Stir in watermelon and serve warm or chill and serve cold.  Makes about 4 cups.
