Creating these Hawaiian Ribs can be a delightful process when followed step by step:

1. Prepare the Marinade: In a mixing bowl, combine pineapple juice, soy sauce, brown sugar, honey, garlic, ginger, black pepper, garlic powder, onion powder, and red pepper flakes (if using). Whisk until well mixed.

2. Marinate the Ribs: Place the ribs in a large zip-top bag or a shallow dish. Pour the marinade over the ribs, ensuring they are well-coated. Seal the bag or cover the dish, then refrigerate for 2 to 4 hours (or overnight for maximum flavor).

3. Preheat the Oven: When ready to cook, preheat your oven to 300°F (150°C).

4. Prepare for Baking: Remove the ribs from the marinade, allowing excess marinade to drip off. Place the ribs on a baking sheet lined with aluminum foil, bone side down.

5. Bake the Ribs: Cover the ribs with another piece of aluminum foil. Bake in the preheated oven for 2.5 to 3 hours until the ribs are tender.

6. Make a Glaze: While the ribs are baking, pour the remaining marinade into a saucepan. Bring to a boil and cook for around 10 minutes until the sauce thickens slightly. Remove from heat.

7. Glaze the Ribs: After baking, remove the foil and brush the thickened marinade over the ribs.

8. Broil for Finish: Switch your oven to the broiler setting. Broil the ribs for 5-7 minutes until caramelized and slightly charred, watching closely to avoid burning.

9. Rest and Slice: Remove the ribs from the oven and let them rest for about 5-10 minutes before slicing between the bones.

10. Garnish and Serve: Sprinkle sesame seeds and chopped green onions over the ribs for garnish. Serve with rice or your choice of side dishes.
