Preheat oven to 180°C/350°F/Gas Mark 4.
Grease a 12 holed muffin tin.

First, make your pastry. Rub the flour, salt and butter together to until it resembles fine breadcrumbs. Use the water to bind it all together to form the pastry and then wrap in cling film and pop into the fridge to chill for at least 30 minutes.

Fry off your pancetta, onions and tomatoes and put to one side. Grill or fry your chipolatas and finely chop them up, then add them to the pancetta, onions and tomatoes. Add the grated cheese into the mixture and the raw egg. Add a pinch of pepper to season and mix it all up together.

Roll out your pastry to about 2cm thickness and cut circles wide enough to line the muffin holes completely to the top. Blind bake the pastry for 10 minutes. Once you’ve done this fill each pie to the top with the filling mixture and then pop back into the oven for 20-25 minutes.

Remove from the oven and let them stand for 10 minutes before removing them to a wire rack. Can be eaten either hot or cold.
