Trim the flap meat (“falda”) because it tends to burn and wrinkle. Remove the membrane from the back of the ribs by inserting a knife under the membrane, lifting it, grabbing it with a paper towel, and pulling it off. Trim excess fat.
In a bowl, combine the paprika, black pepper, salt, brown sugar, granulated garlic, granulated onion, and chile powder. Mix well and transfer to a shaker with wide holes.
Place the ribs on plastic wrap. Drizzle olive oil over both sides of the surface, then spread it evenly. Sprinkle the dry rub evenly on both sides using the shaker.
Wrap the ribs in plastic wrap and place them on a baking sheet or cooling rack to keep them straight. Refrigerate for at least 2 hours or overnight.
Remove the ribs from the refrigerator and bring them to room temperature for 30–40 minutes. Remove the plastic wrap.
Transfer the ribs to aluminum foil, then place them on a rack set over a baking sheet. Preheat the oven to 325°F (165°C). Bake the ribs on the lower-middle rack.
In a saucepan, add the honey, melted butter, soy sauce, mustard, and ketchup. Stir, then add fresh orange juice.
Cook over medium heat, stirring occasionally, until reduced, about 20–30 minutes. Turn off the heat and set aside.
After 1 hour of baking, wrap the ribs tightly with the foil so they cook in their own steam. Bake for another 1 hour.
Open the foil and brush the ribs with the glaze. Return to the oven to finish cooking, about 30 minutes.
Let the ribs rest for 10 minutes before cutting to prevent juices from escaping. Cut into individual ribs and serve.
