Will definitely need to make apple pie myself, now that I have your recipe :P

Double crust pie:
2 cups flour
1/2 teaspoon salt
2/3 cup shortening
6 to 7 tablespoons cold water

flour salt. Cut in shortening till the size of peas, sprinkle in water a table spoon at a time, toss with fork and puh to side of bowl, repeat till all is moist. Devide Dough in half. Half for bottom hlaf to top. Roll out and prep pan, set one hald in pan. Add filling, cover with other half, pinch sides together.

Filling: 6 cups medium/thin sliced granny smith apples.
A table spoon or two flour half cup of sugar, table spoon or so of cinn. Just make it to your taste.

I take it that if I want single crust (say, for an 'open faced' pie) I would half the recipe eh :3

Pretty much. It's all a trial and error thing. Whatever works and feels best to you.

...Dang it, now I'll -have- to do an apple pie :3

In fact, there's a heck of recipe I found online that I've been saving, just for this occasion :P
