In a small bowl, whisk together the Mirin, soy sauce, sesame oil, garlic, ginger, chili garlic paste, honey and pepper. Set aside. Season ribs with a mixture of salt, pepper, garlic powder, and some paprika for a kick. Pat into ribs.
Cut ribs into three equal pieces and place in a resealable bag.
Pour marinade into the bag and marinade in the refrigerator for 8-24 hours.
Remove ribs from the bag, and reserve the marinade for later.
Grill ribs for 4-5 minutes over high heat, then flip and grill for an additional 3 minutes.
Turn heat to low and close lid, letting ribs cook for 10-15 minutes.
While ribs are grilling, pour the reserved marinade into a medium saucepan and bring to a boil until it’s reduced by half, approximately 4-5 minutes then remove from heat.
Brush ribs with the reduced marinade and the Charred Pineapple Bourbon sauce on each side and grill for an additional 2-3 minutes.
Cut ribs apart and arrange on a platter.
Sprinkle with cilantro and sesame seeds before serving.
