Instructions
For the crust:
- In a food processor, pulse flour, sugar and salt until combined. Add butter; pulse until mixture resembles coarse meal, with some pea-size pieces remaining.
- Drizzle 3 tablespoons water over mixture; pulse several times to combine.
- Add more water, 1 tablespoon at a time, and pulse until mixture hold together when pinched.
- Shape dough into an 8-inch square and wrap in plastic. Refrigerate at least 1 hour and up to overnight.
- On a lightly floured surface, roll out dough 1/4 inch thick. Cut dough into about 20 squares (about 1 to 1 1/2 inches each). Transfer to a parchment-lined baking sheet.
- Refrigerate while making filling.
For the filling:
- Preheat oven to 425 degrees.
- Peel, quarter and core apple, then cut into 1/2" thick wedges. In a large bowl, toss together apples, cherries, lemon juice, sugar, flour and spices. Transfer to a shallow 2-quart baking dish.
- Drizzle with 4 tablespoons melted butter.
- Arrange dough squares in a patchwork design over fruit, overlapping as needed to cover.
- Brush remaining 2 tablespoons melted butter over squares; sprinkle with sugar.
- Bake until beginning to brown around edges, about 30 minutes.
- Reduce oven temperature to 350 degrees and continue baking until flaky and golden brown all over and juices are bubbling in center, 40 to 45 minutes more.
- Using the back of a metal spatula, gently press down on dough so it is slightly submerged under fruit.
- Let cool at least 30 minutes.
- Serve with vanilla ice cream, if desired.
