Nigel Slater's Blackberry and Apple Pie

This afternoon I made an apple and blackberry pie, from Nigel Slater's The Kitchen Diaries (pretty similar to this recipe he published in the Guardian). 

I made them with the apples that I was given from a friend at work who had too many to know what to do with: 

And Miskin blackberries I picked on my way home a few weeks ago, and put in the freezer (put them in the freezer before washing them, they're much easier to wash when they're frozen):

It was very tasty and satisfying to make. My first ever attempt at making pastry too!
