Apple-Sour Cream Crumb Pie

Let me start off by saying this pie is not for the faint of heart. After making the pie dough, and the crumb topping, and peeling all the apples, and making the pie filling, this pie is in the oven for an hour and 45 minutes. And then it has to cool for 3-4 hours! This is definitely one of those times that you'd better read the recipe before cracking eggs and finding yourself in the middle of an all-day baking affair. I would advise you to not charge into making this pie on a weeknight, unless you plan on staying up until midnight. BUT, if you get into a fall baking mood over the weekend or if you find yourself with half a day and a hankering for apple pie, then make. this. pie. It is GOOD. I've never had an apple pie with sour cream in it, but it balanced out the sweetness of the golden delicious apples and made for a tasty filling. 

Apple-Sour Cream Crumb Pie
one recipe for pie crust dough, chilled until firm (I use this recipe)

for the crumb topping:
1/2 cup packed light-brown sugar
1/2 cup sugar
1/2 cup flour
1 tsp ground cinnamon
1/4 tsp salt
1 stick cold unsalted butter, cut into small pieces
1 cup walnuts, coarsely chopped (I used pecans instead)

for the filling:
1 cup sugar
1/2 cup flour
1 tsp ground cinnamon
pinch of salt
16 oz sour cream
2 eggs, room temperature, lightly beaten
2 tsp vanilla
6 Golden Delicious apples (about 2 1/2 pounds), peeled, cored, and sliced into 1/4-inch wedges

Roll pie dough into a 15-inch round (1/4" thick) on a lightly floured surface. Fit into a 10-inch pie plate. Trim edge, leaving a 1/2-inch overhang, and fold under, pressing onto rim of pie plate. Use your fingers to create a scalloped edge if desired. Refrigerate until firm, about 1 hour.

Make the crumb topping: whisk together sugars, flour, cinnamon, and salt. Add butter, and combine with a fork or pastry cutter. Stir in walnuts or pecans, and press filling into large clumps with your hands; refrigerate until ready to use.

Heat oven to 450 degrees with 2 racks in lower third.

Make the filling: whisk together sugar, flour, cinnamon, and salt in a large bowl. Stir in sour cream, eggs, and vanilla until thoroughly combined. Add apples, tossing to coat. Place apple mixture in crust.

Place an empty rimmed baking sheet on lowest oven rack to catch any drips, then bake pie 10 minutes. Reduce oven temperature to 350 degrees, and bake until apples are golden brown in places, juices are bubbling, and crust is golden brown, about 45 minutes.

Remove topping from refrigerator, and crumble over hot filling. Bake until topping is browned and set, apples are tender, and bottom crust is thoroughly baked, about 50 minutes. Let cool completely on a wire rack, 3-4 hours.
