Begin your culinary journey by poking the pork belly skin meticulously, then pat it dry with the dedication of a desert explorer wiping off the day's sand.
Mix the kosher salt, white pepper, five spice powder, sugar, and Shaoxing wine. Rub this flavorful mixture onto the meat side of the pork belly.
For the grand finale, rub the skin with the white vinegar, then coat it generously with the cup of kosher salt. This is your secret to the crispiest skin, as crucial as a compass in uncharted territories.
Let your air fryer take the wheel at 200°C (400°F) for about 40 minutes. Watch as the pork belly transforms, much like a stunning landscape unfolding as you travel.
Finally, let your pork belly rest as you would after a long day's journey. Slice, serve, and savor each bite, infused with the spirit of adventure and the comfort of home cooking.
