2 large apples, peeled, cored and chopped (we used Granny Smith)
1 medium yellow onion, peeled and chopped
1/4 cup apple cider vinegar
1/4 cup brown sugar
Zest and juice from 1 small orange or tangerine
1 tablespoon dried ginger
1/2 teaspoon ground cinnamon
Add all ingredients to a nonreactive saucepan and stir to combine. Bring to a boil, reduce heat to a simmer, cover and cook for 35-40 minutes. Uncover and simmer on low for a few minutes more to cook off excess liquid.
Let cool before packing into a storage container and refrigerating.
