Wrapper: In a food processor blend the dry ingredients. Add the sour cream and pulse just until it comes together. Bring it into a ball, wrap in plastic, and chill while you prepare the apples.
Filling: Peel and halve the apples and remove the cores with a melon baller. In a food processor, cream together the sugar, cinnamon and butter. Place a spoonful of this in the center of the apple halves then put the halves together to encase it.
Remove the dough from the refrigerator and roll it out to 1/8-inch thick on a floured surface. Cut into large squares and wrap the apples in it, sealing the edges by painting with milk and pinching. Drop into boiling water with the lemon half in it, cover tightly, and let simmer 15 minutes. Whip the heavy cream, sugar, and sour cream and serve immediately.
