Prepare a medium-hot grill.
In a bowl, mix together the mustard, brown sugar, and bourbon. Rub the pork chops with the garlic and house seasoning, then brush with half the glaze.
Place the chops on the grill. Grill until the chops are slightly charred and cooked, about 20 minutes. Brush with the remaining glaze before serving.
Mix the ingredients together and store in an airtight container for up to 6 months.
