Apple pie ala mode

for the crust:
2 cups all purpose flour
1 teaspoon fine sea salt
1/4 teaspoon ground white peppercorns
3/4 cup Plugra butter, cut into 4-5 pieces
1/2 cup very cold water
for the filling:
4-6 Granny Smith or McIntosh apples (5-6 cups)
1 teaspoon lemon zest
1 tablespoon lemon juice
1/8 teaspoon fine sea salt
3/4 cup brown sugar
1 tablespoon cornstarch
1/4 teaspoon cinnamon
1/8 teaspoon nutmeg
1/2 teaspoon vanilla or vanilla paste or vanilla powder
2 tablespoons butter
ice cream for serving

In food processor with steel chopping blade in place, combine flour, salt and pepper. Add the cold butter and process just until the butter is cut into small chunks. Add the water, and process only until the dough wants to form a ball. Divide the dough into two parts, one slightly larger than the other. Roll out the larger one and place into bottom of pie plate. Preheat over to 450 degrees. Peel, core, and slice apples. In batter bowl, combine apple slices, lemon zest, lemon juice, salt, sugar, cornstarch, cinnamon, nutmeg, and vanilla. Stir gently to coat apples. Pile into bottom crust. Dot with bits of butter. Roll out the top crust, and place on top, cutting steam vents. Trim and crimp the edges together. Sprinkle top with a little milk or cream and a little sugar if desired. Place the pie into microwave oven on high for 10 minutes, then into preheated oven, which you turn down to 375 degrees and bake for about 30 minutes or until crust is brown. Allow the pie to stand at least 30 mintes before slicing. Slice, arrange on serving plates and scoop on a dollop of ice cream.
