My mom has been making these every year for Thanksgiving for as long as I can remember. Its like apple pie, but SQUARE....haha. A lot of work, but definitely worth it!
5 C. flour
2 t. salt
1/4 c. sugar
Combine in a bowl and set aside.
2 c. shortening
2 slightly beaten egg yolks
In a liquid measuring cup, mix egg yolk and milk to add up to 1 1/3 cup. Add to dry ingredients. Add shortening and form into a soft ball handling as little as possible. Divide the dough in half. Roll out the 1st half of dough to fit into a cookie sheet with some up over the sides. (tip from my mom: If you roll the dough on a piece of saran wrap the size of your cookie sheet this keeps the dough from being handled too much.). Extend the dough up the sides of the pan and cut off the excess. Make the apple filling and spoon on top of dough in cookie sheet.
2 quarts peeled sliced apples (8 cups)
1 1/3 c. sugar
5 T. cornstarch
1/4 t. salt
2 t. cinnamon
Mix together and place in cookie sheet on top of dough. "Dot" the top with about 2 T of cold butter.
Roll out 2nd half of dough and place over the top to cover filling, cutting the excess off of the sides. Brush the top with slightly beaten egg whites.
Bake at 375 degrees for 35 minutes and then 250 degrees for 10 minutes. Spread with glaze while warm.
2 c. powdered sugar
2/4 T. water
1/2 t. vanilla
