•200g plain flour, plus extra for dusting
•1 tsp ground mixed spice
•1 tsp ground ginger
•75g dark muscovado sugar
•25g molasses sugar
•100g chopped mixed peel
•½ tsp bicarbonate of soda
•1 tbsp brandy or whisky
•1 egg, lightly beaten
•3 tbsp milk
•A generous pinch of freshly ground black pepper
For the pastry
•200g plain flour
•½ tsp baking powder
•50g butter, chilled and cubed
•50g vegetable shortening or lard, chilled and cubed
1.Make the pastry. Put the flour, baking powder and a pinch of salt in a large bowl. Add the butter and shortening and rub in until it resembles breadcrumbs. Stir in 4 tablespoons of cold water and mix to a soft dough. Cover with cling film and chill while you make the filling.
2.Preheat the oven to 180°C/ fan160°C/gas 4. Mix all the filling ingredients together in a large bowl, with enough milk to just moisten it.
3.Dust a clean work surface with flour. Roll out three-quarters of the dough to a rectangle large enough to line the base and sides of a 900g loaf tin. Drape into the tin and press up against sides, smoothing out any creases. Tightly pack in the filling and press down well. Roll out the remaining pastry to a rectangle large enough to fit the top. Dampen the edge of the pastry in the tin with water, press the pastry lid on top to seal and trim off the edges. Bake for 2 hours. Allow to cool for 1 hour.
4.Remove the black bun from the tin, then cut into slices to serve.
