If you want to have a wicked little snack you will need to pre-order some pork skin from your butcher and you will need to allow a day or two for them to dry out properly. They are worth it....
800g piece pork skin
2 Tbsp sea salt flakes
oil for frying
Cook pork skin in salted water over medium-high heat until very tender (1 hour). Preheat oven to 110C. Drain skin, cool slightly, then scrap off as much fat as possible. Score the skin, place flat skin-side up, on a wire rack, season with salt, then bake until skin cracks (8-10hrs). Cool slightly, then break into pieces.
Pre heat oil in a deep sided pot to 175C (test a little piece first). Carefully fry the scratchings in batches until crisp (1-2 minutes; be careful as the oil may spit). Drain on kitchen paper and sprinkle over sea salt flakes. Cool and serve with a good beer. Store in a airtight container for a couple of weeks.
