Homemade Chinese Roast Pork

Made this today to share with my neighbours, recipe from QM but as usual I altered it ; ))
My secret roast pork rub *evil grin* Ok, I will reveal what's in it:
1. Black peppercorns & Szechuan peppercorns, about 2tbsp each. Fry them (without oil) and grind them into powder
2. Add 1tbsp garlic powder, 2tbsp sea salt, 2tsp sugar & 1 tsp five-spice powder

Score the pork (skin side) as many times as possible piercing into the fat layer. Then scald the skin with hot boiling water(skin only). Cool, rub the seasoning to the pork belly and leave it in fridge uncovered overnight.
Place pork on a roasting rack over a pan of water and bake at 360F for 2 hrs.
After 2 hrs, switch to BROIL and broil at 500F for about 15mins or till puffy!
Cool the meat and cut it with a cleaver skin side down. Enjoy ; ))
