Pat the pork belly completely dry using paper towels. Using a sharp kitchen knife, score crosshatch lines into the skin or fat cap (taking care not to cut through the flesh). Cut the entire slab into uniform 1-inch cubes. Uniformity ensures even rendering and cooking across all bites.
2.Dry-Cure for Maximum Crispiness:Timing: 4 to 12 hours (Chill).
Place the cubed pork belly on a wire rack set over a rimmed baking sheet. Evenly sprinkle the coarse salt and optional baking soda over all sides. Transfer to the refrigerator uncovered for at least 4 hours (overnight yields the best results). This step draws out surface moisture, guaranteeing a crackling texture upon roasting.
3.Apply the Dry Rub:Timing: 5 minutes.
Preheat your oven to 400°F (200°C) for oven roasting, or preheat your air fryer to 375°F (190°C). Remove the pork bites from the refrigerator and pat away any weeping moisture. In a bowl, toss the cubes with the dry rub mixture (brown sugar, smoked paprika, garlic powder, onion powder, black pepper, and spice powder) until every piece is coated.
4.Initial Render & Roast:Heat Intensity: Medium-High (375°F – 400°F) | Timing: 30 minutes.
Arrange the pork belly bites skin/fat-side up on a wire rack lined tray, keeping space between each piece. Roast at 400°F (200°C) for 30 minutes. The fat will begin to render out, leaving behind concentrated flavor while the interior cooks until tender.
5.High-Heat Crisp Finish:Heat Intensity: High (425°F – 450°F) | Timing: 10–15 minutes.
Increase the oven temperature to 435°F (225°C) or crank the air fryer to 400°F (200°C). Roast for an additional 10 to 15 minutes. Watch closely as the outer edges expand and blister into a deep golden, crackling crust. Internal temperature should reach 195°F–205°F (90°C–96°C), indicating collagen has fully broken down.
6.Glaze & Rest:Timing: 5 minutes.
Remove the bites from the oven and let them rest on the wire rack for 5 minutes. If using the Honey-Garlic Glaze, simmer the glaze ingredients in a small saucepan for 2 minutes until bubbly. Lightly toss the pork belly bites in the warm glaze immediately before serving, then top with fresh green onions and sesame seeds.
