Blackberry and Apple Pie

My husband and I have decided to start a vegetable plot on a field which his family owns. At the moment it's mostly covered in brambles, so before we started to clear the ground we picked as many ripe blackberries as we could find. It's early in the season, but we ended up with over a kilogram! Time for pie! :-)

Ingredients (makes a 9 inch pie)
150g cold butter, cubed
275g plain flour
30g icing sugar
1 beaten egg
1/2 tbsp cold water
1 cooking apple, cored peeled and chopped
400g blackberries, washed
75g brown sugar
Beaten egg to glaze

* rub the butter into the flour and icing sugar until it looks like breadcrumbs and there are no big lumps of butter left
* add the egg and water and mix by hand until it forms a dough. Shape into a ball and chill for 30 minutes
* heat the oven to 180C and lightly grease a 9inch pie tin. I bought a disposable foil one since I don't currently own a pie tin
* roll out half the dough to line the tin. Try not to handle it more than you need to
* mix the fruit and brown sugar together and fill the pie base, then roll out the remaining pastry to put on top
* cut off any excess pastry and crimp round the edges of the pie with your fingertips. Make a couple of small holes in the lid to allow steam to escape and glaze the top with beaten egg
* bake for 20-30 minutes or until the pastry is golden and crisp
