To make the pastry, whisk the flour, sugar, salt and spices in a large mixing bowl. Cut in the butter using a hand pastry blender (this can also be done with two knives cutting across each other) just until the mixture is uniformly crumbly.
In a small bowl, combine the molasses and vinegar and stir the wet ingredients into the dry ingredients using a fork. Divide the pastry in half and form into two balls. Wrap one ball in plastic wrap and set aside in the fridge. Roll the other ball on a floured surface and transfer to a 9-inch pie plate and trim and build up the edges, then place this in the fridge.
To make the filling, add the apples to a large mixing bowl. In a smaller bowl, mix the sugar, flour and cinnamon. Pour the dry ingredients over the apples and toss to coat. Add the filling to the pie plate and put back into the fridge.
To form the top crust, roll out the other ball of pastry to a 1/4-inch thickness and use a gingerbread man cookie cutter to make six cut-outs, arranging them over the pie as a top crust leaving vent holes. To finish, brush the top crust with the milk and sprinkled with the sugar.
