Preheat your oven to 400°F (200°C).
Using an apple corer or a small knife, carefully remove the core from each apple, creating a generous cavity. Be sure not to cut all the way through the bottom.
In a medium bowl, whisk together the flour and brown sugar.
Cut in the cold butter using a pastry blender or your fingertips until the mixture resembles coarse crumbs.
Stir in the lemon zest, cinnamon, nutmeg, and chopped raisins until evenly combined. Firmly pack this crumble mixture into the cavity of each apple.
Place the stuffed apples snugly in a medium-sized, shallow baking dish or casserole.
In a small bowl or measuring cup, stir together the brandy, curaçao, and water.
Pour this liquid mixture over and around the apples in the dish.
Bake for 40 to 45 minutes, pausing to baste the apples with the pan juices every 7-10 minutes. The apples are done when they are tender when pierced with a knife and the filling has puffed up and caramelized on top.
Carefully remove the dish from the oven and let the apples cool for about 15 minutes. The caramelized sugar on top will form a hard crust; you can gently remove this cap if desired. Spoon the remaining syrupy liquid from the pan over the apples.
Serve warm, either plain or with a generous drizzle of chilled heavy cream.
