- 6 cups fresh marionberries
- 3/4 cup white sugar
- 6 tablespoons all-purpose flour
- 1 tablespoon lemon juice
- 1 (15 ounce) package pastry for a 9-inch double crust pie
- 2 teaspoons water, or as needed
- 2 teaspoons sugar, or to taste
- Preheat oven to 450 degrees F (230 degrees C).
- Mix marionberries, 3/4 cup sugar, flour, and lemon juice together in a large bowl until well-combined.
- Fit the bottom of a 9-inch pie plate with 1 pie crust. Pour in marionberry mixture. Cover with second crust; crimp edges to seal. Brush pie lightly with water. Sprinkle 2 teaspoons sugar on top. Cut four to eight 1-inch slits in the top crust with a knife.
- Bake in the preheated oven for 10 minutes. Reduce heat to 350 degrees F (175 degrees C) and continue baking until crust is golden, 45 to 50 minutes more. Let cool completely before serving, about 1 hour.
