3 c. flour
3/4 tsp. salt
3/4 tsp. baking powder
1 c. and 2 tbsp. shortening
3 egg yolks, beaten
1 1/2 tsp. lemon juice
3/4 c. cold water

Sift together dry ingredients. Cut in shortening as for pie dough. Combine egg yolks, lemon juice, and water; add to flour mixture. Mix thoroughly. Dough will be very moist. Do not add more flour. Divide into 2 parts. Roll out on well floured board and line bottom and sides of a 15 x 10 inch pan.

Apple Filling: Pare and slice 8 or more large apples thinly. Using hands, coat thoroughly with mixture of 3/4 cup sugar, 1/2 teaspoon salt, 2 tablespoons flour, 1/2 teaspoon cinnamon, and a dash of nutmeg. Arrange in crust-lined pan and cover with top crust. Seal edges. Make decorative slits. Bake at 375 degrees for 1 hour. While warm, ice with mixture of 1 cup confectioners' sugar, 1 tablespoon milk, and 1 tablespoon lemon juice. Cool before cutting into squares.
