Thread 2 or 3 cubes of pork onto each skewer. Sprinkle each skewer on all sides with salt, black pepper and seasoned salt, and set the skewers aside.
Whisk eggs and milk together in a bowl. Place the seasoned breadcrumbs in another bowl. Pour 475ml of water into a 20x30cm baking dish with a wire rack set in the dish, and set the dish aside.
Heat oil in a deep-fryer or large saucepan to 180 C / Gas 4.
Dip each skewer of pork into the egg mixture, then dip in crumbs; dip the skewers a second time into egg mixture and then crumbs. Gently lay the skewers, a few at a time, into the hot oil, and brown until the coating is crisp and golden brown, about 3 minutes per side. Set the fried skewers aside while you finish the rest. Once the skewers are all browned, set them on the wire rack in the baking dish. Cover the dish tightly with aluminium foil.
Carefully place the baking dish with the skewers into the preheated oven, and bake until hot and no longer pink in the centre, about 20 minutes. Remove the foil, and bake 10 minutes more to dry out the crumb coating. Serve hot.
