Since to many people asked me for the recipe on Facebook. Here is the recipe my husband uses for the filling of the Apple Sauce Pie:
1 cup apple sauce made from tart apples
1 cup sugar
1/2 cup melted butter
2 tablespoons flour
1/2 teaspoon vanilla powder
2 tablespoons lemon juice
1 9inch pie shell
Sorry he is not giving up his secret pie crust recipe....
Stir all the ingredients together.
Bake at 350 degree preheated oven for about 45 minutes or until nice crispy sugar crystals appear on top.
