Apple, Walnut, and Gorgonzola Crostata

From an episode of Giada at Home:

Ingredients
Crust:
1 1/2 cups all-purpose flour
1/2 teaspoon kosher salt
1 tablespoon granulated sugar
3 tablespoons unsalted butter, cut into small pieces
1/2 cup mascarpone cheese
1 1/2 tablespoons lemon juice
3 tablespoons ice water

Filling:
3 tablespoons unsalted butter, melted
4 small Granny Smith apples, peeled, cored, and cut into 1/4 to 1/2-inch thick slices
1/4 cup granulated sugar (I used 1/8 cup dark brown and 1/8 cup white sugar. Dark brown sugar has such a caramely flavor.)
3/4 teaspoon ground cinnamon
1 tablespoon fresh lemon juice
1 teaspoon lemon zest
1/2 cup chopped walnuts
1/3 cup crumbled Gorgonzola

1 large egg, lightly beaten

For the crust: In a food processor combine the flour, salt, and sugar. Pulse to combine. Add the butter and pulse until the butter is finely chopped and the mixture resembles a coarse meal. Add the mascarpone cheese and lemon juice and pulse a few times. Add the ice water and run the machine just until the mixture is moist and crumbly, but does not form a ball. Do not over mix. Turn the dough out onto a sheet of plastic wrap. Press into a disc, cover, and refrigerate for 30 minutes.

For the filling: Place an oven rack in the lower third of the oven. Preheat the oven to 400 degrees F. Melt the butter in a large nonstick skillet over medium heat. Add the apple slices, sugar, and cinnamon. Cook, stirring frequently, until the apples are softened, but not mushy, about 5 minutes. Set aside to cool for 10 minutes. Stir in the lemon juice, lemon zest, walnuts, and Gorgonzola.

Cut a piece of parchment paper to fit the inside of a 12 by 17-inch baking sheet and place on a work surface. Place the chilled dough on the parchment paper. Roll the dough out into an 11-inch circle, about 1/4-inch thick. Lift the parchment paper and transfer to the baking sheet. Spoon the apple filling into the center of the dough. Spread the filling evenly, leaving a 2-inch border. Fold the dough border over the filling to form an 8-inch round. Pleat the edge of the pastry and pinch to seal any cracks in the dough.

Using a pastry brush, brush the crust with the beaten egg. Bake until the crust is golden, about 25 minutes. Cool for 10 minutes before slicing and serving.


This was right tasty but when I make it again I'll do a few things different:
* Use a different apple. Granny Smiths are tart. Tart, tart. I'd use a combination of Golden Delicious and Red Rome.

* Dust the pastry with a sprinkling of raw sugar before baking. It'd give the crust a nice, sugary crunch.

* Still with the apples...I'd up the sugar to about 1/3 to 1/2 cup even using a sweeter apple.

* I'd add just a touch of freshly grated nutmeg.
