1. Prepare the pastry

    Gently melt 100g lard and 100g butter in a pan with 200ml hot (not boiling) water. Sieve 500g plain flour, 50g white bread flour and 1 tsp salt into a bowl, then pour in the lard, mix and stir in quickly. Add 1 beaten egg and 2 tsp English mustard. Mix to make a smooth, soft pastry. Cover and chill for 10 mins. Meanwhile, cut a circle of nonstick baking paper the same size as the base of the tin.

  2. Raise the pastry

    Generously flour the outside and bottom of a 20x5cm solid-base cake tin. Wrap ¼ of the pastry in baking paper; set aside in the fridge. Put the rest on a floured baking tray. Roll to a circle 28cm in diameter. Place the tin on the circle of baking paper, in the centre of the pastry, and raise the pastry up against the sides of the tin to the top. Smooth, trim, and reserve the offcuts.

  3. Wrap the pastry

    Use 4 layers of nonstick baking paper to make a collar the same height as the pastry. Wrap around the sides and firmly secure the bottom, middle and top with kitchen string, so the sides are supported. Transfer to the fridge and chill on the tray for 30 mins, or until firm. Preheat the oven to gas 6, 200°C, fan 180°C.

  4. Prepare the filling

    Mix 500g skinless pork belly (chopped into 1cm pieces), 270g pork lardons, 500g pork shoulder, minced (or 500g pork mince), 2 thinly sliced onions, 8 finely chopped fresh sage leaves, 2 tbsp fresh thyme leaves, ½ tsp ground nutmeg and 1 bay leaf; season. Roll out the remaining pastry to a 5mm thick x 22cm wide circle for the lid. Shape the offcuts into leaves. Remove the pie crust from the fridge and ease it from the tin using a hot palette knife. Remove the tin and circle of baking paper, leaving the pastry and collar. Spoon in the filling, pressing down to level.

  5. Add the lid

    Brush the rim with cold water, top with the lid and crimp the edges. Lay the leaves on top and make a small hole in the centre. Brush with beaten egg. Bake for 
1 hr, then reduce the temperature to gas 4, 180°C, fan 160°C and cook for another 30 mins, or until crisp. Remove the paper; brush the sides with beaten egg. Bake for another 30 mins, until the juices run clear and a metal skewer inserted into the centre feels hot. Cool for 20 mins.

  6. Set the pie

    Soak 6 gelatine leaves in cold water until pliable. In a pan, heat 150ml (5¼fl oz) chicken stock until simmering. Remove from the heat; stir in the drained gelatine and 2 tsp English mustard. When the gelatine has dissolved, add 150ml (5¼fl oz) chicken stock. Add the stock mixture to the pie. To do this use a funnel inserted into the pie hole and fill gradually, until full.

  7. Serve and enjoy

    Once at room temperature, chill the pie overnight. It will keep for up to 5 days.
