gonna try that Jim, I like a bit of shoulderFarm shop rare breed pork is the business. Loads of good fat and great crackling. Tesco pork is the worst. They trim off what little fat it had to start with and they and even trim the rind off belly pork. That's the best bit. The good stuff is more expensive but it's worth it. I opted for a premium shoulder of pork for Christmas dinner last year. Scalded the skin with boiling water first then rubbed in plenty of salt. It was magnificent.
And it's great cold with bubble and squeak and some pickles.
