I have a pork shoulder joint for tomorrow and I'd like to cook it in the slow cooker. So far I've only cooked casseroles - smaller pieces of meat with veg - and am a bit unsure how to cook a joint of meat. I'm guessing pork shoulder would be nice done in the slow cooker as it is a cut best cooked slowly. But how do I cook it? Do I add liquid? how long to cook it for? It is a 1.3kg boneless joint. Help please!
