This Cantonese roast pork belly delivers juicy, well-seasoned meat beneath a deeply crisp, blistered crackling. With a simple overnight dry and a slow roast-finish under the broiler, it is a restaurant-style pork dish you can make at home.
Rinse the pork belly and pat it completely dry. Place it skin-side down on a tray, then rub the Shaoxing wine over the meat only, avoiding the skin.
In a small bowl, mix the salt, sugar, five-spice powder, and white pepper. Rub this seasoning mixture evenly over the meat side, then turn the pork skin-side up.
Using a sharp metal skewer or meat pricker, poke the skin all over without piercing too deeply into the meat. The more small holes you make, the better the skin will blister and crisp.
Refrigerate the pork belly uncovered for 12 to 24 hours to dry out the skin. This step is key for achieving crisp crackling.
Preheat the oven to 375°F. Set the pork belly on a foil-lined baking tray and fold the foil up around the sides to form a snug border about 1 inch high, leaving the top exposed.
Brush the skin evenly with rice wine vinegar. Spread the coarse sea salt over the skin in a solid, even layer so the surface is fully covered.
Roast for 1 hour 30 minutes, or 1 hour 45 minutes if the pork belly still has the rib attached. The salt crust will protect the skin while the meat cooks through.
Remove the tray from the oven and switch the broiler to low. Carefully scrape off the salt layer and unfold the foil so the sides are exposed.
Return the pork belly to the oven on the lowest rack and broil for 5 to 10 minutes, watching closely, until the skin puffs and turns deeply crisp. Rotate the tray if needed for even blistering, but do not let the skin burn.
Transfer the pork belly to a cutting board and rest for 15 minutes. Slice with a serrated knife or heavy chef's knife and serve while the skin is still crisp.
For the best crackling, make sure the skin is very dry before roasting and keep the seasoning on the meat side only. If you cannot find Shaoxing wine, dry sherry is a good substitute. Store leftovers refrigerated for up to 3 days and reheat in the oven to help re-crisp the skin.
