His pie is filled with nectarines, blueberries, blackberries, banana and apple. Mine had apples and blackberries - take away from this that any old fruit/ combination there of will do!
I make my pastry with wholemeal flour and brown sugar, both of which contribute to a more nutty tasting, brown effect. The brown sugar helps to counter the slightly drying effect of the bran in the flour.
I chuck a little ground almonds in through my fruit, partially because I like the taste, but mostly to soak up any extraneous fruit juices!
This is a deceptively simple, but impressive dessert - I encourage you to give it a go!
