1. Combine the flour, sugar, salt, and butter in a food processor and process for about 5 seconds. If you do not have a food processor, freeze the butter and grate.
2. Sprinkle the ice water over the flour mixture and process until the pastry comes together. If you are not using a food processor, knead the dough. Transfer the pastry to a work surface, gather it, and pat it into a disk. The butter does not have to be combined entirely; it will melt during baking. This part is optional; wrap the pastry in plastic or wax paper and refrigerate until chilled. This step ensures the crust bakes up with flaky layers. However, you can also roll out the pastry and use it immediately.
3. Peel, halve and core the apples and slice them crosswise 1/4 inch thick. Set aside the best-looking apple slices for a more decorative top layer. In a small bowl, combine the sugar and cinnamon.
4. Preheat the oven to 400°F. Roll the pastry to a 12- x 14-inch rectangle on a lightly floured work surface and transfer to a baking sheet (lined with parchment paper). Spread the chopped apples over the pastry to within 1 inch of the edge. Drizzle the honey over the chopped apples. Arrange the apple slices on top in decorative circles in overlapping rows. Sprinkle the cinnamon sugar evenly over the apples and add a few tablespoons of chopped butter pieces of butter. Fold the pastry edge over the apples to create a 1-inch border.
5. Bake for about 1 hour, until the apples are tender and the pastry is nicely browned and crisp. Once it's finished, let it cool for about 10 minutes. Serve warm with a scoop of vanilla ice cream or jam for a breakfast treat. Add a tablespoon of honey before serving (optional).
