nectarine and blueberry pie

Dear Kurt,

It’s been a summer of pies! Sorry to have ruined grocery-store pies for you. But now I know why I never liked pies before, the store bought ones have such awful crusts! This summer was a big turning point for me. I used to pick cake over pie, but now I’m very much in the pie camp as well. Here’s one of the many pies that I managed to document this summer. The nectarines can also be swapped out for peaches in this case.

Nectarine and Blueberry Pie
All-butter pie crust recipe adapted from The Four & Twenty Blackbirds Pie Book
Makes one 9-inch pie (double crust)

1 teaspoon kosher salt
3 teaspoons granulated sugar
½ pound (2 sticks) cold unsalted butter, cut into 1/2-inch pieces
2½ cups unbleached all-purpose flour
¼ apple cider vinegar
1 cup cold water

You can make the pie dough by hand, but I like to use my trusty food processor for its speed. Plus, it evenly distributes the butter into small specks among the flour.
Add the sugar and salt into the food processor. Then cut up the cold butter and scatter them around the bowl. Pour in the flour and then pulse until the mixture is grainy and sandy looking.
In a measuring cup, pour in the apple cider vinegar and cold water.
Turn on the food processor again and through the opening, add 10 tablespoons of the apple cider vinegar and water mixture.
The dough should come together nicely and feel a little (a tiny bit) tacky or sticky. I prefer the dough this way because additional flour gets added during the rolling process.
Divide the dough into two flat discs and wrap with plastic. Refrigerate overnight or for at least 2 hours.

Pie Filling
Filling recipe from The Four & Twenty Blackbirds Pie Book
Makes enough for one 9-inch pie

7 nectarines, diced (1 pound or 3 cups)
2 cups of blueberries
¼ cup granulated sugar
½ cup packed brown sugar
2 tablespoons fresh lemon juice
3 tablespoons potato starch
½ teaspoon ground allspice
Pinch ground cloves
½ teaspoon salt

Combine the nectarines, blueberries, granulated sugar, brown sugar, and lemon juice together. I like to let it sit for 30 minutes to an hour for the excess juice to come out. I’ll pour out the majority, but keep a quarter of the juices. Then add the potato starch, ground allspice, ground cloves, and salt. Give it a good mix.

Pie Assembly Time

Unsalted butter
2 tablespoons of flour
1 large egg
Brown Demerara sugar

Butter the pie pan and let it chill in the fridge. When you’re ready to roll the pie dough, take one out of the fridge and let it sit for about 5 minutes. Remember, you don’t want it too warm, but just pliable enough to roll.
Dust a surface and rolling pin with flour (about 1 tablespoon). Roll the dough out to about a 11 or 12-inch circle to take into account the pan’s height. Having dough hanging off the edge of the pan is okay. At this point, if you think the dough is getting too soft, pop it back in the fridge.
After covering the bottom of your pan with the dough, pour in the nectarines and blueberries. Let it chill in the fridge and take out the second disc of dough to work on the pie lattice. This is also a good time to start preheating your oven to 425°F, make sure to position the oven racks to the bottom and center positions.
Again, dust a flat surface and rolling pin with flour (another 1 tablespoon). Roll the dough out and cut them into strips or whatever shaped design you’d like.
I made a bunch of long rectangle strips and did a simple twist braid going vertically. And no braids going horizontally. Don’t trim off the excess yet!
To make the border, roll in all the excess dough hanging off the edge. You’ll soon have a nice thick circumference that can be crimped into a wave. Again, if the dough starts to feel warm, pop it back in the fridge, especially if your oven hasn’t finished preheating yet!
Once your oven indicates that it’s ready, take the pie out of the fridge. Scramble the egg in a small bowl and brush it over the dough. Careful not to draw out any of the fruit if your lattice top has huge gaps.
Then sprinkle the Demerara sugar on top, it should stick to the egg wash.
Place the pie on a baking sheet on the lowest rack of the oven. Bake for 20 to 25 minutes.
Lower the oven temperature to 375°F and move the pie on the baking sheet to the center oven rack. Continue to bake for 30 to 35 minutes. The pie is ready when the crust is golden brown and the juices are bubbling.
Take the pie out and let it cool on a wire rack for 2 to 3 hours. Serve at room temperature. The pie will keep refrigerated for 3 days or at room temperature for 2 days.
