Mixed Berry Crostata
Ingredients
For the Pastry Dough:
- 2 cups all-purpose flour
- ½ tsp. salt
- ½ cup confectioners sugar
- 12 tbsp. unsalted butter, cold and cut into cubes
- 1 large egg yolk
- 2 tbsp. ice water
For the Filling:
- 4 cups mixed berries (blackberries, blueberries and raspberries)
- 1 tbsp. cornstarch
- ⅓ cup granulated sugar
- Juice of ½ lemon
- 1 tbsp. cold unsalted butter, cut into small pieces
- Egg wash
- Coarse sugar, for topping
Instructions
To prepare the pastry dough:
- Combine the flour, salt and powdered sugar in the bowl of a food processor.
- Add the butter and pulse until it forms a coarse meal.
- Add the egg yolk and ice water; pulse just until the dough comes together.
- Gather the dough together and divide into two equal size pieces.
- Form each piece into a disc and place on a piece of plastic wrap.
- Wrap tightly and refrigerate for 1 hour or overnight.
- If chilled overnight, allow the dough to rest at room temperature for 15 to 20 minutes before rolling out.
To assemble the crostata:
- Place the berries in a large mixing bowl.
- In a small bowl or measuring cup, whisk together the cornstarch and sugar; pour over the berries.
- Add the lemon juice and toss to combine.
- On a lightly floured, clean work surface, roll each disk into a 10-inch round.
- Transfer the disc to a parchment lined baking sheet.
- Repeat with the remaining dough.
- Mound half the berry mixture in the center of a dough round leaving a 2-inch border.
- Fold the edges of the dough up, overlapping as needed, covering part of the fruit.
- Scatter half the diced butter on top of the fruit.
- Refrigerate the assembled crostatas for 30 minutes.
- Pre-heat oven to 375°F.
- Brush the dough edges with a lightly beaten egg and sprinkle with coarse sugar.
- Place in the pre-heated oven and bake the crostatas until crust is golden brown and the fruit is bubbling; about 45 to 50 minutes.
- Remove from oven and allow to cool before serving.
Notes
Do not make the dough rounds any larger than 10 inches in diameter; the dough will be too thin and not hold together well.
All butter crusts must remain cold; chilling after assembling is important.
As an alternative to making the pastry dough, Pillsbury pie crusts are an excellent substitute.
