Preheat your oven to 150°C (300°F). Line a baking sheet with foil and place a wire rack inside it to elevate the ribs. This setup ensures even slow roasting and easy cleanup.
Pat the pork ribs dry with paper towels to remove excess moisture. Carefully slide a butter knife under the thin membrane on the back of the ribs and peel it off—this helps the seasonings penetrate and keeps the ribs tender.
Mix together salt, black pepper, garlic powder, smoked paprika, and chili powder. Rub this dry spice mixture all over the ribs generously, pressing it into the meat for flavor penetration. Let the ribs sit for about 15 minutes while the flavors meld.
Place the ribs on the wire rack, bone-side down, and slide into the oven. Roast slowly for 2.5 to 3 hours, until the meat is tender and pulling back from the bones slightly.
Meanwhile, combine soy sauce, honey, brown sugar, minced garlic, liquid smoke, and rice vinegar in a saucepan. Bring the mixture to a gentle simmer over medium heat, stirring constantly until the glaze thickens slightly—about 5-7 minutes. It should be glossy and sticky.
Once the ribs are cooked and tender, remove them from the oven. Using a basting brush, generously coat the top of the ribs with the thickened glaze. Turn on the oven's broiler to high (around 220°C/430°F).
Broil the ribs for 3-5 minutes, keeping a close eye. The glaze should bubble and turn a deep amber color, forming a crackly, glossy crust. If the glaze starts to burn, reduce the broiler heat or remove from the oven sooner.
Flip the ribs carefully with tongs, then brush more glaze over the underside. Broil for another 2-3 minutes to develop a crackling, sticky exterior that gleams beautifully.
Remove the ribs from the oven and let them rest on the rack for about 5 minutes. This allows the juices to redistribute, making the meat tender and juicy.
Slice the ribs between the bones to serve, optionally garnishing with chopped herbs or sesame seeds. The ribs should be sticky, glossy, and crackling on the outside, with tender meat inside ready to enjoy.
