In a small bowl, combine butter and Kingsford® Smoked Hickory Dry Rub then mix to blend well. Refrigerate prepared butter if not using right away.
Next, build a charcoal fire for direct cooking using Kingsford® Charcoal and preheat the grill to 400 degrees Fahrenheit.
Meanwhile, prepare the pork. In a small bowl, combine Kingsford® Smoked Hickory Dry Rub and ground coffee, and mix well. Season pork medallions with the BBQ coffee dry rub then grill for approximately 5 minutes per side until they reach an internal temperature of 145 degrees Fahrenheit. The last few minutes of cooking, use a pastry brush to slather pork with Kingsford® Brown Sugar Applewood BBQ Sauce.
Remove pork medallions from the grill and lightly slather with a Kingsford® Brown Sugar Applewood BBQ Sauce. Top each medallion with BBQ butter before serving. Sprinkle top with parsley and salt, if desired.
