For a special supper, slow-roast a pork shoulder. Start the roast in the morning, and it will be ready for dinner. The skin crisps to crunchy cracklings, and the meat melts with juicy tenderness. Serve it with carrots butter-steamed in a slow-cooker, then finished with cream and olives. Add sauteed kale or a frisee salad and bread to round out the menu.
