Combine sugar, the 2 TBS flour and nutmeg in a saucepan. Blend in the lemon-water mixture. Cooking until thickened and stirring constantly.
Add apples and butter.
Sift together the cup of flour and the salt into a mixing bowl.
Cut in the shortening until the particles are like small peas.
Sprinkle 3-4 TBS cold water over the mixture, a little at a time, while tossing and stirring lightly with a fork. Add water to the driest particles, pushing lumps to the side until dough is just moist enough to hold together. Form into a ball.
Flatten dough to about 1/2 inch, smooth at edges. Roll out on floured surface. Cut into diamond or triangles. (We use cookie cutter shapes my boys choose).
Pour hot apple filling into well greased pie pan.
Arrange pastry shapes over filling.
Bake in a pre-heated oven at 400 degrees F for 35-45 minutes.
