1 1/4 c. flour
3/4 tsp. grated lemon peel
1/2 tsp. salt
1 stick chilled, unsalted butter, cut into 12 pieces
3 1/2 tbsp. cold water
1 1/2 tsp. fresh lemon juice

FILLING:

2 Golden Delicious apples
1 Granny Smith apple
2 tsp. fresh lemon juice
2 tsp. Apple Schnapps or Calvados
1/4 c. sugar
1/2 tsp. cinnamon
1/4 tsp. nutmeg
3 tbsp. chilled, unsalted butter

Pastry: Blend flour, lemon peel, and salt in processor. Add butter and cut in until mixture resembles coarse meal. Combine cold water and lemon juice. With machine running, add through feed tube and process until dough begins to gather. Gather into a ball, then flatten into a disk. Wrap tightly and refrigerate 30 minutes.

Filling: Peel and core apples. Cut into 1/8 to 1/4 inch slices. Toss with lemon juice and Schnapps (in large bowl). Combine sugar, cinnamon, and nutmeg in small bowl. Roll dough into 13 inch round on lightly floured board (do not trim edges); transfer to baking sheet. Place apples on pastry, leaving a 2 inch border of pastry all around. Sprinkle apples with sugar cinnamon mixture. Dot with butter. Fold pastry border up over apples. Middle will be uncovered. Bake at 425 degrees for 15 minutes, then reduce to 375 degrees for 35 minutes or until pastry is golden and filling bubbles. Using 2 spatulas, transfer carefully to cooling rack. Dust edges with powdered sugar. Serve warm or at room temperature.
