Instructions
For the Crust
- In a large mixing bowl, whisk together the flour, sugar, and salt until well combined. Add the cold cubed butter and cold vegetable shortening. Using a fork, cut them into the dry ingredients until you have small pea-sized crumbs.
- Slowly drizzle in some of ice water at a time (you may not need the full 1/2 cup) and gently mix it in until the dough starts to come together. Turn the dough out onto a lightly floured surface and pack it into a ball. Cut the dough in half and flatten it into two discs and add to pie tin.
Make the Filling
- Add berries, sugar, and lemon juice to a large saucepan over medium heat. Simmer, until warm and juicy, about 5-10 minutes, gently stirring occasionally.
- Spoon out about ½ cup of the juice from the pan into a bowl. Stir cornstarch into the juice until smooth.
- Bring the pot of berries back to a simmer and slowly pour in the cornstarch. Gently stir mixture until thickened, about 2-5 minutes.
- Remove from heat and stir in the butter. Allow to cool for 15 minutes. Pour mixture into unbaked pie shell. Add a whole top with holes pricked on top for steam to escape.
- Pinch the edges of the top and bottom pie crusts together and crimp the edge, if you like. Brush a thin layer of beaten egg white over the top of the pie and sprinkle lightly with sugar.
- Bake at 400 degrees F for 40-45 minutes. Check it after about 25 minutes and place a piece of tinfoil over it if the top crust is getting too brown.
- Remove to a wire cooling rack and allow to cool for several hours. Once completely cooled, you can cut into it or cover it and refrigerate it overnight to serve the next day.
