Pre-heat the oven to 210°C / 410°F.
Remove your pastry from the packaging and place in a pie dish (mine was 28cm / 11").
Bake your crust blind for 15 minutes. In the meantime, prepare your filling: add all of the ingredients to a pan and cook for about 10 minutes, just until the fruit soften and the sauce thickens.
Take the pie out of the oven and turn it down to 180°C / 356°F.
Remove whatever you have used to bake your pie blind, and then set back in the oven for a further 5 minutes.
When ready, pour over the berries, spreading to give a nice, even coverage. Top with your jammy biscuits and return to the oven for about 20-25 minutes (if you notice that the biscuits and crust are browning a little too much cover the pie with foil).
Remove from the oven, and allow to cool a while. Eat warm or cold. When ready to eat, sprinkle with a little icing sugar for decoration. Serve with cream or ice-cream. Enjoy!
