This is a fun recipe my mother came up with sometime ago.
Pastry:
9 oz plain flour
1 tsp salt
6 oz unsalted butter, cold, cut into small pieces
4 tbsp ice water, plus more if needed
Zest of 1 unwaxed lime – finely chopped
1 egg
Fruit Filling:
3 cups fresh blueberries
2 cups cherries, quartered
2 cups white currants
¼ cup unrefined caster sugar
¼ cup cornflour
1 tbsp Lime Juice
Method
Sift the flour and salt together in a large bowl, stir in the lime zest, using a round bladed knife, cut the butter into the mixture until it resembles fine breadcrumbs. Gradually add the iced water until the dough just holds together - without being wet or sticky. Test by squeezing a small amount of the dough, if the pastry is still too crumbly add a little more water – a dessertspoon at a time
Turn the dough out onto a clean work surface, divide in half, and place each half on a piece of cling film. Shape into disks, wrap in cling film and refrigerate overnight
Roll out the dough between two pieces of cling film into a 12” circle. Take off one piece of cling film and use the second to fit the pastry into an 8” pie plate, pressing around the edges. Trim pastry leaving a ½” overhang. Fold edge of dough over or under, and crimp. Roll out remaining dough to the same size, place on a baking sheet and place both pieces of pastry into a refrigerator to chill – for about 45 minutes
Put the different types of fruit into separate bowls
Place the sugar, cornflour and Lime Juice into a small jug and stir to combine, divide between the three bowls and stir to combine.
Spoon the blueberries around the outside of the pastry case, add the white currants next, place the cherries into the centre, ensuring the mixture is nicely rounded towards the centre of the pie
Remove the second piece of pastry from the refrigerator and cut into ½” strips, lay across the pie making a lattice – cut off any excess and crimp the edges
Break the egg into a small bowl and whisk. Lightly brush with the beaten egg and refrigerate for an hour
Preheat the oven to 200 degrees Celsius and place a baking tin on a shelf in the lower half of the oven
When the oven is up to temperature, place on the baking sheet and bake until the crust begins to turn a light golden brown, approximately 15 minutes, reduce the temperature to 180° Celsius, bake for another 45 minutes – turning the pie twice during the cooking time. The crust should be golden brown and juice thickened and bubbling
Transfer the pie dish onto a wire rack to cool completely
Best eaten on the day it is baked, or keep a maximum of 2 days covered with cling film
