Roast Pork English style

My flatmate, Aa, likes to make roast pork to satisfy his everlasting craving for fat and crackling. Its relatively easy to make.

To achieve a nice crackling, make sure you pat dry all the moisture with some kitchen towel and rub liberal amounts of coarse salt all over the skin. Preheat the oven to 250 degrees initally and bring it down to 170 just as you pop it into the oven.
Aa likes to rub some ground cumin seeds and cracked black pepper into the skin to give it nice flavour.
Leave it in for for approximately 30mins for every 500g of meat.
Don't forget to rest it for 5mins before carving itso that the juices are retained within the meat.
