Canned Apple Pie

Never use flour to can apple pie.

Uh, what if I used flour to can apple pie in 1993.

20 years ago?

Well, the apples were technically from 1992.

I don't think you should use them.

What if I top the whole pie with icing?

They should be ok then.  
Apple Slices

My husband grew up enjoying what they called apple slices.  I see lots of recipes for it now called apple slab.  Basically what it is is a thin apple pie topped with glaze.  I think the point is to get the least amount of fruit and most amount of pastry and icing.  If you have a favorite apple pie, use that recipe only instead of a pie plate bake it in a 9x13 pan.  While it is still warm top with a powdered sugar glaze.  For a 10x15 inch pan keep the filling the same but 1 1/2 times the pie crust and icing recipe.  For a large 12x17 inch pan, double the pie filling recipe, the crust recipe and the icing recipe.  For the larger pan sizes the baking time is the same as the smaller pans.  Here is the recipe using Mrs. Field's apple pie recipe.  
Yield: 12 bars 

Preheat oven to 400°F.

3 cups all-purpose flour
2 tsp grated lemon zest (1 medium lemon)
1 cup salted butter, chilled
6-8 Tbs ice water, more if needed

I add 1 t. salt and leave out the lemon zest. I don't know if the salt would be needed if you added the zest.

6 large Granny Smith apples, peeled and thinly sliced (about 4 cups) I like to use Golden Delicious
1 cup white sugar
1 tsp ground cinnamon
1/4 cup cornstarch
1/4 cup salted butter, chilled and cut into small pieces 

2 cups powdered sugar 

4 T. hot water
1 t. vanilla extract

To prepare crust:
Mix flour and lemon zest together with wire whisk in a medium bowl. With pastry cutter or 2 knives, cut in butter with flour until dough resembles coarse meal.
Add ice water and blend until dough can be gathered into a ball. Divide dough in half, flatten into disks, and wrap tightly in plastic wrap or a plastic bag. Refrigerate 1 hour or until firm.

To prepare filling:
Combine sugar, cinnamon and cornstarch with a wire whisk in a large bowl. Add apples to sugar mixture and toss with a wooden spoon until dry ingredients coat the apples completely.

On a floured surface use a floured rolling pin to roll out dough.  Place dough into a 9x13 inch pan.  Leave only a small edge up the sides.  It doesn't matter if you have to place the dough in the pan in pieces.  No one will see it.  Spoon in apple filling evenly over the dough.  It should be a single layer.  Sprinkle butter pieces on top.

To prepare top crust:
Roll out second piece of dough.  Place the dough on top of the filling.  Again,  the dough can be placed on top in pieces.  It will be covered with icing.   

Place pie on center rack of oven. Bake for 20 minutes, then reduce oven to 350°F. Bake an additional 30 minutes, or until crust is deep golden brown and filling is bubbling through the cracks. 

Meanwhile make the icing by combining all ingredients in order.

Remove from apple slices from oven and while it is still warm spread the icing over the entire top.  Serve warm or room temperature.
