Step 1

Preheat grill to medium (350°F to 400°F). Sprinkle pork evenly with pepper and salt. Whisk together jam, maple syrup, vinegar, and Worcestershire sauce in a small bowl; measure ¼ cup glaze into a separate small bowl, and reserve for serving.

Step 2

Place pork on oiled grates; grill, covered, turning and brushing with glaze occasionally, until a thermometer inserted into thickest portion of meat registers 140°F, 14 to 16 minutes. Remove pork from grill, and let rest 10 minutes. Slice pork, and serve with reserved ¼ cup glaze for drizzling.
