Ingredients:
- 2.5 cups all-purpose flour
- 1 cup unsalted butter, chilled and cubed
- 1 tsp granulated sugar
- 1 tsp salt
- 8 tbsp ice water
- 6 cups fresh raspberries
- 0.75 cup granulated sugar
- 0.25 cup cornstarch
- 1 tbsp lemon juice
- 1 tbsp lemon zest
- 0.25 tsp ground cinnamon
- 1 tbsp unsalted butter
- 1 egg
- 1 tbsp coarse sparkling sugar
Instructions:
- In a large bowl, whisk together the all-purpose flour, 1 tsp granulated sugar, and salt.
- Add chilled butter cubes to the flour mixture. Use a pastry cutter to work the butter into the flour until the mixture resembles coarse crumbs with some pea-sized lumps remaining.
- Drizzle in ice water one tablespoon at a time, stirring with a fork until the dough just holds together when pressed.
- Divide the dough into two discs, wrap in plastic, and refrigerate for 1 hour to relax the gluten.
- In a medium bowl, stir together the 0.75 cup granulated sugar, cornstarch, and ground cinnamon.
- Gently fold in the fresh raspberries, lemon juice, and lemon zest, stirring carefully to keep the berries whole.
- Let the filling sit for 10 minutes to allow the thickener to begin hydrating.
- Roll out the first dough disc and fit it into a 9-inch deep-dish pie plate. Pour in the raspberry filling and dot the top with 1 tbsp of butter.
- Roll out the second dough disc to cover the pie. Seal the edges and cut small vents in the top crust.
- Brush the crust with beaten egg wash and sprinkle with coarse sparkling sugar.
- Bake for 50 minutes until the crust is golden brown and the filling is bubbling.
