Pre-heat the oven to 140°C
Heat the lard in a cast iron casserole pan and then sauté the onions for 10 minutes or until soft but not browned.
Add the paprika powder and still in the fat and the onions for about a minute until well incorporated.
Add the diced pork and cook until it loses its raw colour, and then add the tomato paste and cook for 1 minute.
Add just enough water to cover the pork and increase the heat until the water is simmering gently. Do not allow to boil or the meat will become chewy.
Put the lid on the casserole pan and place it the into the oven and slow cook for about 2.5 hours or until the meat is tender.
