Yes Yes Yes! Chinese Roast Pork Belly is one of our favorite treat meals! Can't have it too often because its too fatty, but I absofreakinglutely love this. I bought a piece today to make for our Chinese New Year meal tomorrow night.
What you should do is first of all lay it out flat on a baking sheet (I use foil on my sheet because it makes it easier to clean) then you need to take a SUPER sharp knife and score it into squares (makes it easier to cut when you are eating it also) Salt it heavily and leave it for maybe an hour or two, then I wipe it with a paper towel, you can repeat this if you want. Then I sprinkle all sides quite liberally with Chinese Five Spice Powder and pop it into a hot oven (maybe 200 degrees) for maybe 90 minutes (depending on how big and whatever the package says. The top should go gorgeous and crispy and the layers of fat and meat will melt together.
Now, this months BBC Good Food Magazine has a spread on doing pork belly, I can't find it on their website, but if you can get the March issue now, you can read about it.
Good Luck! I want to know how it comes out!
