In the UK pork rinds are called Pork Scratchings and are usually in the crisps and snack section at the supermarket, they are very cheap here though, about 35-55p a bag. It is possible to make your own though!!, you need pork skin from the butcher, dehaired in poss, get him to take as much fat as possible off the back and cut into thin strips. All you need to do then is salt linberally and put in a very hot oven until raosted and crisp. You may want to pour off any fat as it roasts so that it gets so crisp that all the fat has been drained off. Drain on kitchen paper and use as per recipe. Good luck!!
