Preheat oven to 425°F and arrange the bottom pie dough into the pie pan. Use a small fork to prick holes in the dough; set aside until ready to fill.
15 ounces refrigerated pre-made pie crust
Drain the cherries, reserving 1 cup of cherry juice.
43.5 ounces Red Tart Cherries packed in water
In a medium saucepan set over medium heat, whisk the sugar and cornstarch together. Slowly, while still whisking, add reserved cherry juice. Stir until smooth. Add salt and cinnamon, stirring constantly, until the mixture comes to a low boil. Simmer the mixture, stirring often, for about 7-9 minutes or until it has thickened.
1 cup granulated sugar, 3 tablespoons cornstarch, 1 cup cherry juice, ½ teaspoon kosher salt, ⅛ teaspoon ground cinnamon
Remove the mixture from the heat and add the butter, almond extract, lemon zest, and lemon juice. Stir well. Pour the mixture into a medium bowl and allow the mixture to cool slightly.
1 tablespoon unsalted butter, ¼ teaspoon almond extract, ½ lemon
Pour the cooled pie filling into the prepared pie crust and cover the filling with a vented or lattice top crust. Use a pastry brush to brush the crust with milk. Sprinkle liberally with coarse sugar, if desired.
1 tablespoon cold milk or cream, Demerara sugar
Bake at 425°F for 20 minutes, then reduce the temperature to 375°F and bake another 35-45 minutes (covering the edges when needed with aluminum foil or a pie crust shield). The crust should be a beautiful caramel brown and the juices should bubble up through the lattice top.
Serve with a scoop of vanilla ice cream, if desired.
