Pre heat the oven to 180°C fan assisted (gas mark 4) or 200°C
without a fan
Rub the butter and lard into the flour with a pinch of salt
using your fingertips or a food processor, then blend in 6 tbsp
cold water to make a firm dough
Cut into 4 equal sections, then chill for 20 mins
Mix together the filling ingredients
Roll out each piece of dough on a lightly floured surface until
large enough to make a circle about 24cm across - use a bowl to
trim it to shape
Divide the filling into approximately 100g balls then place the
filling in the centre of each round, leaving a margin at each
end
Brush the pastry all the way round the edge with beaten egg,
carefully draw up both sides so that they meet at the top, then
pinch them together to seal
Lift onto a non-stick baking tray and brush with the remaining
egg to glaze
Bake for 30 minutes until a light golden colour, leave to cool
on a wire rack a little before eating
Serve with sweet onion pickle
Jeff's note:
You could make a dozen or so small turnovers instead which would
go great with drinks when entertaining guests.
