For the pie dough: Mix together the flour, sugar and salt, and then combine with the butter in a food processor until the butter is in pea-size crumbles. Chill the mixture in the refrigerator for at least 30 minutes. Preheat the oven to 350 degrees F.
Add ice water into the dough by hand or in a food processor until the dough is hydrated and can be smooshed (with a little force) into a ball.
For the sour cherry filling: Mix together the cherries, pears, sugar, cornstarch, flour, cinnamon, ginger and salt.
For the crisp topping: Mix together the flour, sugar, butter, baking powder, salt and eggs until just combined.
For assembly: Roll out the dough and press into a large pie plate. Fill the dough with the sour cherry filling, and then press the crisp topping on top of the fruit. Bake for 30 minutes.
