In the bowl of a food processor fitted with the metal blade, pulse together the flour and almonds until nuts are coarsely ground. Add in the Redpath Dark Brown Sugar, oats, cinnamon, and salt. Pulse until well mixed. Add in the cubed butter; process just until crumble begins to clump together. Transfer contents into a small bowl and place into the fridge until needed.
In a medium bowl, whisk together the Redpath Golden Sugar, tapioca starch, ground cardamom, salt, and ground cloves until thoroughly blended.
In a large bowl, toss together the cubed peaches, lemon juice, and pure almond extract until fruit is well-coated.
Pour the sugar mixture over the peaches. Toss to coat.
Transfer the coated peaches into chilled pie crust. Sprinkle the crumble over the peaches.
Whisk together the egg and heavy cream or water. With a pastry brush, lightly brush the egg wash on the braided crust.
Place pie into the preheated oven and onto the baking sheet. Bake at 400℉ (204℃) for 20 minutes. Reduce heat to 375℉ (191℃) and continue to bake for another 45 to 50 minutes, or until the crust is deep golden in colour and the filling is bubbling.
Carefully remove pie from the oven. Transfer to a wire rack to cool completely before attempting to slice; at least 3 hours. Alternatively, cool pie to room temperature and place into the fridge to chill until the filling is cooled to 85℉ (29℃).
