Roasted Pork Chops with Serrano Ham Vinaigrette

Cook bacon in large skillet over medium heat until fat is rendered, about 6 minutes. Remove bacon and reserve for another use. Transfer 1/3 cup bacon drippings to measuring cup (add vegetable oil to measure 1/3 cup if necessary). Boil broth in heavy small saucepan until reduced to 1 cup, about 10 minutes. Set aside. Heat 1 tablespoon oil in medium nonstick skillet over medium-low heat. Add shallot; sauté until tender, about 3 minutes. Add chopped ham, then brown sugar and vinegar. Increase heat to medium; stir until mixture is syrupy, about 2 minutes. Add reduced broth; boil until slightly reduced, about 3 minutes. Pour through strainer into same small saucepan; discard solids in strainer. Set vinaigrette aside.
