How to Make It
Place a rack in bottom third of oven and preheat to 400°F. Mist a 9-inch pie plate with cooking spray and line a large, rimmed baking sheet with foil.
Place apples in a large bowl. In a smaller bowl, combine flour, cornstarch, salt, cinnamon and 1 Tbsp. sugar; sprinkle over apples and toss to coat slices evenly.
Melt butter in a large skillet over medium-high heat. When foaming subsides and butter turns light golden, add brown sugar and walnuts. Cook, stirring constantly, until sugar melts and walnuts are lightly toasted, 3 to 4 minutes. (Be careful: The mixture can burn easily.) Add raisins and stir to coat. Pour in calvados; it will bubble and spatter. Reduce heat to medium and cook, stirring constantly, until mixture becomes syrupy, 2 to 3 minutes. Pour mixture over apples and toss to coat.
Roll out half of dough into a 12-inch circle; press into pie plate. Spoon apple mixture into crust, mounding in center. Roll remaining dough into another 12-inch circle. Brush edge of bottom crust with water; gently place top crust over apples. Trim and crimp edges decoratively to seal. Cut a few slashes in top to allow steam to escape. Brush top with cream; sprinkle with 1 Tbsp. sugar. Place pie on lined baking sheet and bake until crust is golden brown and filling bubbles through top, 45 to 55 minutes. Let cool on a wire rack for at least 20 minutes; serve.
