Step 1:

• Prepare the marinade by combining the dried osmanthus flowers, honey, soy sauce, hoisin sauce, rice vinegar, minced garlic, grated ginger, five-spice powder, and sesame oil in a large bowl.
• Mix well to ensure all ingredients are thoroughly combined.

Step 2:

• Season the pork ribs with salt and pepper. Place the ribs in the bowl with the marinade, making sure they are well-coated.
• Cover the bowl with plastic wrap and let the ribs marinate in the refrigerator for at least 1 hour, or preferably overnight for more intense flavor.

Step 3:

• Preheat your oven to 350°F (175°C). Remove the ribs from the marinade and place them on a baking sheet lined with aluminum foil.
• Reserve the marinade for later use. Cover the ribs with another sheet of aluminum foil to keep them moist during baking.

Step 4:

• Bake the ribs in the preheated oven for 1 hour. After 1 hour, remove the top layer of foil and brush the ribs with the reserved marinade.
• Increase the oven temperature to 400°F (200°C) and bake for an additional 30 minutes, basting the ribs with the marinade every 10 minutes until they are nicely glazed and caramelized.
