Heat the lard or butter in a medium sized saucepan. Add the onion and fry for 10 mins over a low-medium heat until softened. Add the swede, carrot and celery and fry for 5 mins.

Stir in the meat, if using leftover roast lamb or beef, then the potatoes. Pour over the stock and season generously, bring to the boil, then turn the heat down to a simmer. Cook covered for 1 hr 30 mins or until the vegetables have softened and the potatoes have broken down completely. If you’re using corned beef, add this to the pan 20 mins before the end of cooking. Serve with oatcakes, or crusty bread
