In a saucepan over medium heat, add apple cider vinegar, brown sugar, ginger, star anise, cloves, pepper, cardamom & sea salt. When mixture starts to bubble, fold in about 2 cups sliced peaches. Bring the mixture to a boil; turn down heat to a lively simmer. Cook, stirring often, 20-30 minutes, or until mixture has thickened enough to easily coat a spoon. Set aside to cool.
