Whisk 2 cups flour and salt together in a large bowl; cut in lard with a knife or pastry blender until the mixture resembles peas. Add 1/4 cup cold water, 1 tablespoon at a time, tossing with a fork, until mixture is moistened just enough to form a ball when squeezed. Divide dough into two pieces, form each into a ball, and refrigerate until cold, about 1 hour.
Place berries and 1/2 cup water in a saucepan; bring to a boil. Reduce heat and simmer berries until tender, about 10 minutes.
Whisk sugar, 1 1/2 tablespoons flour, and cornstarch together in a small bowl. Stir sugar mixture into berries, return to a boil, and cook, stirring constantly, until filling is clear, about 2 minutes; stir in lemon juice. Cool filling to room temperature, about 30 minutes.
Preheat oven to 425 degrees F (220 degrees C).
Roll one ball of pastry out on a lightly floured surface to fit an 8-inch pie plate; line pie plate with crust. Pour berry mixture into pie crust; dot with butter. Roll remaining pastry out for top crust, place over filled pie, and crimp edges tightly together.
Bake in the preheated oven for 15 minutes; reduce oven temperature to 350 degrees F (175 degrees C) and bake until crust is golden brown and filling is bubbly, about 35 minutes.
Saskatoon berries may be called serviceberries in some markets.
Cook's Note:
Mixing the pastry dough can also be done in a food processor. Pulse flour with lard until it is the size of small peas. Turn mixture into a bowl and proceed.

This is such a good pie! We found Saskatoons on a walk, stopped and picked a full bag of them, and went straight home and put them into this pie. Wouldn't change a thing.
