1 tablespoon sugar (sugar in the raw, honey or agave)
1 tablespoon balsamic vinegar
1 teaspoon fresh lemon juice
1/4 teaspoon grated lemon peel
Instructions
In a 1-quart saucepan simmer the onion in the olive oil over medium-low heat until tender.
Add the thyme, cinnamon, rosemary, cardamom, salt and pepper to the tender onions. Cook for 1 minute.
Add the blueberries and arrowroot to the spices and increase the heat to medium. Stir and cook until the berries begin to simmer/low boil and release their liquid.
Reduce heat to simmer; add the sugar and balsamic to the blueberries and simmer. Use a spoon or potato masher to break some of the berries. Simmer for 8 minutes.
Add the lemon juice and peel to the berries. Remove from heat and allow to cool.
Notes
An optional addition is fresh, grated ginger. Keep refrigerated for 1 week or freeze.
