Saskatoon Pie

Ingredients

• 6 cups All purpose flour
• 2 tsp Salt
• 1 cup Unsalted Butter
• 1 cup Vegetable Shortening
• 1 large Egg
• 1 tablespoon Vinegar
• Splash Water
• 5 Cups Saskatoon Berries
• 1/2 cup Sugar
• 3 tablespoons Cornstarch

Instructions

1. To make the pastry, place the flour and salt in a large bowl. Add the butter and vegetable shortening and rub them into the flour until the mixture resembles coarse flakes with a few pea-sized pieces remaining.
2. In a measuring jug, lightly beat the egg, add the vinegar and enough ice-cold water to reach the required volume. Stir the liquid into the flour mixture just until the dough begins to come together, taking care not to overmix.
3. Turn the dough out onto a lightly floured surface, form into a ball and divide into five equal portions. Shape each into a disc and wrap tightly. Chill two discs for at least one hour and freeze the remaining discs for future use.
4. Preheat the oven to 350°F / 180°C. Position the oven rack in the lower third and place a foil-lined baking sheet on the rack below to catch any drips.
5. Roll out one chilled disc into a circle about 12 inches wide and line a 9-inch pie plate, allowing the pastry to overhang the edges.
6. For the filling, place the Saskatoon berries in a bowl and toss gently with the sugar and cornstarch until evenly coated. Spoon the mixture into the prepared pastry shell.
7. Roll out the second disc of pastry and cut it into wide strips. Arrange the strips over the filling in a lattice pattern, weaving them over and under. Fold the overhanging base pastry over the lattice ends and crimp or press to seal.
8. Brush the lattice with egg wash and sprinkle lightly with sugar. Place the pie on the prepared baking sheet and bake for 90–100 minutes, until the crust is golden and the filling is bubbling.
9. Remove from the oven and allow to cool completely on a wire rack. Serve warm or at room temperature with whipped cream or ice cream. Store covered in the refrigerator for up to four days.
