Preheat oven to 400ºF.
In a mixing bowl, combine apples, cranberries, brown sugar, ginger, cinnamon, nutmeg, lemon juice, and salt.
Roll out the pie dough and cut out 4 rounds that are slightly larger than the mouth of the baking dishes. Fill dishes with apples. Top each ramekin with a round of pie dough and crimp the edges with the tines of a fork. Brush the crust with egg wash. Transfer baking dishes to a baking sheet. Bake until the crust is golden brown and the apples are tender, about 20-30 minutes. Serve warm or at room temperature plain or topped with vanilla ice cream or whipped cream.
