Apple Crostata with Oat Crumble Topping
This recipe is really a cross between a pie and a crostata (“pietata,” anyone?). Whatever you call it, it’s my mom’s hard-captured recipe, worth every bit of the wrestling I had to do to get it down in print! This recipe makes enough dough for two, 9.5-inch pie pans (or crostatas), but the filling is just enough for one. You can freeze the unbaked dough for up to two months. If you don’t want to use a pie pan for this recipe, roll out your dough into a large circle (about 11-12 inches) then place it on a baking sheet. Add the apple filling to the center of the dough, and fold and pleat it all the way around as you would if you were following the instructions below.
Instructions
- 1
For the dough:
- 2
Add the flour to a large bowl along with the salt and sugar and sift together.
- 3
Add the Crisco to the dry ingredients. With your fingers or a pastry blender, mix the ingredients together. Add the water to the dough, a little at a time, and continue to mix until it looks like a course meal and there are several pea-sized clumps that form.
- 4
Continue to mix the dough until it’s soft enough to form a dough ball.
- 5
Split the dough into two equal portions and form them into disks. Wrap the disks in plastic wrap and refrigerate them for about an hour.
- 6
For the apple filling:
- 7
Add the apples to a large mixing bowl. Mix in the sugar and 3/4 cups of water and coat well. Strain the liquid from the apples and place the liquid in a small saucepan.
- 8
Meanwhile, in a small bowl, mix together the cornstarch and 1/3 cup of water until smooth.
- 9
Bring the liquid in the pan to a boil. Once boiling, add the cornstarch mixture, a little at a time, until the liquid thickens. Remove from heat.
- 10
Pour the thickened mixture over the sliced apples and mix well to coat. Allow this mixture to stand for at least 30 minutes.
- 11
Begin preparations to roll out your pie dough:
- 12
When you’re ready to form your crust, lightly flour your work surface and then the top of the dough, too. Start rolling out the dough with a rolling pin, moving it in one direction, starting at the middle of the dough, away from you. Rotate the dough a few times and continue the same rolling motion. The dough should be about 1/8-inch thick and about 3 inches larger than the size of your inverted pie pan.
- 13
When you’re ready to move the dough to the pie pan, roll it over your rolling pin and unroll it over the pie pan. Let the dough settle to the bottom of the pan and gently press it down with your hands (you can also lightly bang the pan on your counter and rotate it). There should be about 3 inches of extra dough around the edges.
- 14
Add the apple mixture evenly across the bottom of the pie pan. Dot the top of the mixture with the 1 tablespoon of chilled butter pieces.
- 15
Fold the overhanging dough toward the center of the pie, pleating it all the way around. There should be a portion of the filling (in the middle) that will be exposed. Preheat your oven to 400 degrees F.
- 16
For the crumble mixture:
- 17
In a small bowl mix together the dry ingredients. Add in the pieces of chilled butter and mix well with your hands to incorporate it.
- 18
Sprinkle the crumble mixture over the exposed filling, mounding it slightly. Use your fingers to press the crumble down a bit.
- 19
Lightly moisten the top of the crust with a bit of water and dust it with a little sugar.
- 20
Bake the pie for 15 minutes at 400 degrees F., then reduce the heat to 375 degrees F. and bake for 45 more minutes, or until the crust is golden and the apple mixture is bubbly
