You can also use apple juice with spices if you don't have apple cider on hand. For the spices use 1/2 teaspoon cinnamon, 1 cinnamon stick, 1/8 teaspoon of each - nutmeg, cloves, allspice, and cayenne pepper. For the caramelized onions, slice two onions thin. Use the same pan you seared the pork in and turn to medium heat, sauté the onion in the pork fat, stirring every 5 minutes for 15-20 minutes. For the sautéed apple, combine 1 crisp apple, sliced, with 1/4 cup of the cooking liquid from the pork and sauté over medium low heat.
