I adapted this from Bon Appetit who adapted it from Chez Panisse. I am not a comfortable pie crust maker but this wasn’t so hard. And like I said, a good workout! The original recipe called for Granny Smiths but only in season in the fall in LA – try Pink Ladies.
1 cup all purpose flour
¾ cup white whole wheat flour
1/4 teaspoon salt
3/4 cup (1 1/2 sticks) chilled unsalted butter, cut into 1/2-inch cubes
2 tablespoons (or more) ice water
3 – 4 apples, peeled, cored, cut into 1/8-inch-thick slices*
3 - 4 tablespoons sugar, divided
1 heaping tablespoon lemon zest
1/4 cup apricot preserves
1 egg or whole milk for a wash
Blend flour and salt in processor. Add butter and blend, using on/off turns, until mixture resembles coarse meal. Add 2 tablespoons ice water and blend just until dough begins to clump together, adding more ice water by teaspoonfuls if dough is dry. Gather dough into ball; flatten into disk. Wrap in plastic and chill 1 hour. DO AHEAD: Can be made 2 days ahead. Keep dough chilled. Soften slightly at room temperature before rolling out.
Roll out dough between sheets of parchment paper to 1/8-inch-thick round, 14 inches in diameter. Remove top sheet of parchment. Chill 15 minutes. Using bottom sheet as aid, transfer dough on parchment to large unrimmed baking sheet.
Preheat oven to 450°F. Combine apple slices, 2 tablespoons sugar, and lemon peel in medium bowl; toss to blend. Spread preserves over crust, leaving 1 1/2-inch plain border. Arrange apple slices in concentric circles atop preserves, overlapping slightly. Using parchment as aid, fold plain crust border up over apples, pleating and pinching any cracks in crust. Brush crust with an egg wash or milk. Sprinkle crust edges and apples with remaining 2 tablespoons sugar.
Bake galette 20 minutes. Reduce oven temperature to 375°F and continue baking until crust is golden, about 30 minutes longer. Remove from oven. Slide long thin knife between parchment and galette. Let stand at least 10 minutes. Cut into wedges and serve warm or at room temperature.
