In a medium-sized bowl, whisk together the flour, salt and baking soda
In a separate, large bowl with electric beaters, whip together the sugar and butter until creamy
Quickly incorporate the flour mixture into the butter/sugar mixture with electric beaters until crumbly. Make sure not to overmix.
Drizzle about ¼th cup water into the crust, working the mixture with your hands until the crust holds together. Form into a ball and lightly press into a disk form.
Cover the disk in plastic wrap and place in the freezer while you begin to prepare the filling
Preheat oven to 375-degrees
For the Filling
Mix apples and lemon juice to prevent browning.
In a bowl, blend sour cream, ricotta, eggs, and sugar, and pour over the apples to completely cover them.
Pull crust out of the freezer and knead it into a pretty oven-safe dish – bake for ~20 minutes (I usually place spoons on top of the dough to prevent it from bubbling up while baking)
Pour entire apple/sour cream/ricotta mixture into the baked pie shell
Crank up the oven to 400 degrees – place the pie in the oven until pie filling rises and apples brown. Remove from oven. Trim overhang.
Prepare Topping:
While filling is baking, place the chopped walnuts, flour, butter, cinnamon, and brown sugar in a mixing bowl Mix well until all ingredients have a crumb like texture and there are no large lumps.
Place the crumb topping over the baked filling and crust.
Beat the yolk and water to make an egg wash and brush the crimped rim of the pie crust with the egg wash.
Set pie on the middle rack of the oven and bake for 20 to 30 minutes at 350 degrees. Pie is done when juices are bubbling through the topping and the apples are tender.
Serve warm or cool, topped with whipped cream or vanilla ice cream.
