2and 1/2 cups plus 1 tablespoon all-purpose flour, divided
1/4cuplight brown sugar, packed
1stick (4 ounces) unsalted butter, VERY cold and cut into tiny pieces
1large egg, beaten
1/2cup(full-fat) sour cream
2medium apples, peeled, cored, and cut into bite-sized chunks (about 1 and 1/2 cups)
1cupsalted caramel sauce
Flaky sea salt, for sprinkling, optional
Preheat oven to 400°(F). Line a large baking sheet with parchment paper or a non-stick baking mat; set aside. In a large bowl combine 2 and 1/2 cups of the flour, salt, baking powder, baking soda, brown sugar, cinnamon, ginger, and nutmeg; mix well, making sure no large clumps of brown sugar remain.
Cut the butter into small cubes then quickly work it into the mixture (using a pastry cutter or two forks) until it resembles a coarse meal; set aside.
In a small bowl, whisk together the egg, sour cream, and milk, then add to flour and butter mixture. In a small bowl combine apple cider and apple chunks, then add in the remaining tablespoon of flour and toss to coat. Gently fold the apple chunks, and any remaining flour, into dough with a spatula until just combined.
Pour the shaggy mixture out onto a clean, floured work surface and shape the dough (you will have to work/knead it quite a bit to get it together) into an 8-inch circle. Cut the dough into 8 wedges and carefully transfer them to the prepared sheet. Bake for 22-24 minutes, or until cooked through and the tops are golden brown. Drizzle with salted caramel sauce, sprinkle with sea salt (if using), and serve at once!
