For the pork shoulder, place into a vacuum bag and seal. Cook in a water bath set at 67°C for 48 hours. Alternatively, preheat the oven to 200°C/gas mark 6. Place the shoulder into a roasting tray and cook for 30 minutes, then turn down the heat to 130°C/gas mark 1 and cook for 4 hours until meltingly soft. Whichever way you cook the shoulder, the bone should be easily removed from the meat, which can then be pressed between 2 trays with a weight on top. Refrigerate overnight
