Bedfordshire clangers

Method

1. To make the pastry, in a large mixing bowl, rub the flour and suet together with your fingers until it resembles breadcrumbs. Add a pinch of salt, then slowly pour in 100-150ml cold water, mixing, until the dough comes together into a ball (you might not need all the water). Wrap, then chill for at least 30 minutes in the fridge.
2. For the pork filling, add the butter, onion and apple to a saucepan over a low heat. Cook for around 10 minutes until the apple and onion are very soft. Add the mace, membrillo and a pinch of salt and pepper, then cook and stir until the membrillo melts. Transfer to a tray, spreading out the mixture so it cools quickly.
3. Once cool, combine with the pork mince and breadcrumbs. Fry off a small portion to check the seasoning, if you like. Once you’re happy, cover and chill the pork filling in the fridge until needed.
4. For the apple filling, add the bramley apples, sugar and membrillo to a medium saucepan (one with a lid) with a splash of water. Cook over a medium heat, covered, until the apples completely break down into a purée (about 10 minutes). Add the sliced eating apples, mix well, then leave to cool. Chill until needed.
5. Heat the oven to 190°C/170°C fan/gas 5. Take the pastry out of the fridge, unwrap and, on a lightly flour-dusted surface, roll into a large rectangle, roughly the thickness of a pound coin. Cut out 10 rectangles, roughly 12cm x 9cm, saving any trim to create the central barriers. Add 1 tbsp of the pork filling to one side and 1 tbsp of the apple filling to the other, leaving a 1cm barrier around the outside and a little gap in the centre. Add a small piece of pastry between the fillings, then brush the edges of the pastry with a little water. Fold the dough over the filling, then use a fork to seal the edges.
6. Brush the clangers with the beaten egg yolk, put them on a lined baking tray, then bake for 25 minutes until golden and a skewer pushed into the pork side comes out hot. Allow to cool for a few minutes, then enjoy – or leave to cool and enjoy at room temperature.
