Preheat oven to 450°. Liberally sprinkle pork all over with salt.
Put pork in a large roasting pan (crowding is okay). Coat all over with toasted sesame oil, then with hot pepper oil.
Roast for about 20 minutes. Then reduce to 350° and roast 2 to 2 1/2 hours, periodically pouring off fat (have a heatproof bowl handy for this), until pork belly is crisp on top but still juicy within.
Serve the strips on a large wooden cutting board. Chop a couple of them into bite-size pieces to convey the idea, and serve with a knife so everyone can cut their own chunks.
