1. Prepare a charcoal grill to medium-low heat (you should be able to hold your hand just above the cooking grate for 5 to 6 seconds).
2. To make the glaze, place all glaze ingredients in a pot and reduce until the consistency is thick and sticky. Once you reach this consistency, take the glaze off the heat and blend with a stick blender to a smooth finish. Set aside.
3. Pat the short ribs dry, season with salt and place on the charcoal grill. Cook through well.
4. Once cooked, brush the ribs all over with the glaze. Allow to rest for 30 minutes before serving.
