Step 1 In a heavy, 3-quart non-reactive pot, combine the apples, onion, ginger, cider vinegar, orange juice, sugar, salt, chipotle, raisins and currants. Bring the mixture to a boil over high heat, stirring frequently. Reduce the heat to a gentle simmer and continue to cook until the mixture is reduced and thickened, 35 to 45 minutes, stirring occasionally to prevent the ingredients from sticking to the bottom of the pot. Remove from heat.
