The only apples I'll use for pies are Northern Spy. They are getting harder to find every year, but they are the BEST! Here's the recipe that I've used for many, many years:
PERFECT APPLE PIE
6 to 8 Northern Spy Apples, peeled & sliced thin
3/4 to 1 cup sugar
2 tablespoons flour
dash salt
1-1/2 teaspoon cinnamon
1/4 teaspoon nutmeg
Combine dry ingredients & mix with apples. Turn into pie shell & dot with butter. Sprinkle top crust with milk and sprinkle sugar over top. Bake at 400 degrees for about 50 minutes.
Here's a bonus recipe for you too:
SOUR CREAM APPLE PIE
3/4 cup sugar
2 Tbs. flour
1 cup sour cream
2 to 3 cups finely chopped apples (Northern Spy)
1 beaten egg
1/2 tsp. vanilla
1/8 tsp. salt
Mix well and add apples. Pour into pastry lined pie pan and bake about 40 minutes in 350 degree oven.
Prepare topping mix while pie is in the oven. Remove from oven and sprinkle with topping:
TOPPING: Using a pastry blender, combine the following:
1/3 cup sugar (1/2 white & 1/2 brown sugar)
1 tsp. cinnamon
1/3 cup flour
4 Tbs. chilled butter
NOTE: Using a pastry blender and chilled butter (not room temperature) work best to make a crumbly mixture - on the dry side.
Return to 325 degree oven for 15 to 20 minutes.
