1
Make the crust: Pulse the flour and salt in a food processor to combine.
-
2
Add 2 tablespoons butter; pulse a few times until the mixture looks like cornmeal.
-
3
Add the remaining 4 tablespoons butter and pulse until it is in pea-size pieces.
-
4
Add the cream cheese; pulse a few more times until the dough just comes together.
-
5
Add the vinegar and 1 tablespoon ice water; pulse a few times until the dough is moist.
-
6
Divide the dough between two pieces of plastic wrap.
-
7
Shape each into a disk and wrap.
-
8
Refrigerate until firm, at least 1 hour or overnight.
-

Put a baking sheet on the middle oven rack and preheat to 425 degrees F for 30 minutes.

Meanwhile, make the filling: Peel the apples and slice about 1/4 inch thick; toss with the berries, granulated sugar, flour, vanilla, butter and salt in a large bowl.

Set aside.

12
Roll out 1 disk of dough into a 12-inch round on a lightly floured surface.

Ease into a 9-inch pie plate.

Fold the overhanging dough under itself.

Add the filling.

16
Roll out the remaining disk of dough into an 8-inch round on a lightly floured surface; slice into 12 strips.
-
17
Brush the strips with some of the beaten egg.
-
18
One at a time, twist the strips of dough and, working from the center of the pie outward, arrange the strips on the pie to make one continuous coil.
-
19
Brush the top of the pie with the remaining beaten egg and sprinkle with the turbinado sugar.
-
20
Transfer the pie to the hot baking sheet in the oven and bake 15 minutes.
-

Reduce the oven temperature to 350 degrees F and continue baking until the crust is golden and the filling is bubbling, 50 to 55 more minutes.

(Tent with foil if the crust browns too quickly.)
