Apple Squares

3 egg yolks
2 cups flour
pinch of salt
1/2 # margarine
2 tablespoons vinegar
6 graham crackers, crushed
12 apples, cored, peeled and cut into slices
1 cup sugar
1 tsp cinnamon

Cut flour into margarine, pie crust style. Add egg yolks and vinegar and
mix well. Divide dough in half and refrigerate several hours or overnight
till firm.
Roll out one piece and dough and line a greased 8 x 13 pan with it (make
sure the dough reaches the tops of the sides). Sprinkly the graham cracker
crumbs over the bottom.
Mix apples with the cinnamon and sugar and fill the crust. Tope with the
second piece of dough and seal the edges. Use a fork to poke holes
randomly over the top to let steam escape. If desired you can brush the
top with melted butter and a light dusting of sugar.
Bake at 400 degrees for one hour or until deep golden brown.
