Baked Apple Dumplings

To make the dough: In a medium-sized bowl, whisk together the flour, baking powder, salt and sugar (or whisk the sugar into the self-rising flour)., Cut in the butter until the mixture is crumbly, using your fingers, a pastry fork or blender, or a mixer, leaving some pea-sized pieces., Sprinkle in the smaller amount of milk, and stir. Add a bit more milk as needed, just until the dough comes together., Divide the dough in half, wrap each half in plastic, and put it in the freezer to chill., To prepare the apples: Wash, peel and core the apples, saving the peels., Slice the apples in half around the equator. Sprinkle the 8 apple halves with 1 tablespoon lemon juice (to keep them from browning), then set them aside., To make the syrup: Combine the brown sugar, water, and apple peels in a medium-sized saucepan, bring to a boil over medium heat, and simmer for 10 minutes., Combine the sugar, cinnamon and nutmeg in a small bowl., Preheat the oven to 375°F.

Stir in the lemon juice and boiled cider., Pour this syrup evenly over the dumplings.
