Cherry Pie With Frozen Cherries

0 Prepare the pastry: place the flour, sugar and salt into the bowl of a food processor and pulse several time to combine.
1 Next, add the diced cold butter to the flour mixture and continue to pulse until the butter resembles small pea sized pieces.
2 While the food processor is running pour in cold water until a dough begins to form.
3 Transfer the dough to a bench and bring the dough together, divide in half and form 2 discs.
4 Wrap in plastic wrap and chill in the fridge for at least an hour.
5 Meanwhile prepare the filling by mixing the sugar, lemon juice, zest, cornstarch, almond extract and frozen cherries.
6 Stir continuously over a low heat until the mixture has thickened, this may take between 8-10 minutes.
