Serves 4. Try to use fresh pork and not frozen pork if possible, to avoid the pork urea smell. Cooking apples refer to more tart apples, i.e. Golden Delicious, Granny Smith, Gravenstein, or Royal Gala in a pinch. Resembles the asian curry puff :)
For pastry, mix flour and salt in a bowl. Lightly rub in butter/margarine until mixture resembles fine breadcrumbs.
Sprinkle a tablespoon of water over the mixture, mix to form a dough, adding up to 3 tablespoons of water. Knead lightly and chill.
Mix together the remaining ingredients and season to taste.
Divide pastry into quarters, roll each piece out to a 15cm circle. Divide filling between circles, dampen edges with water and bring together over the filling. Seal, pleat edges and place on greased baking tray.
Brush with milk, bake in preheated oven, 200C (Gas 6) for 20 minutes. Reduce heat to 180C (Gas 4), bake further 20-30 minutes. Serve hot.
