Pern bubbly pies

Crust: 
1/2 cup butter or margarine 
2 tablespoons granulated sweetening 
2 1/2 cups flour 
1/2 teaspoon salt 
1/2 cup ice water 
Cut the butter into chunks. Combine the dry ingredients in a bowl. Work the butter gently into the dry mixture with a fork until pieces the size of peas form. Sprinkle the water over and work it in. (Do not overwork the dough.) Form the dough into a ball. 

Filling: 
5 cups blueberries (or one 20-ounce package, frozen) 
1 cup granulated sweetening 
1/4 teaspoon powdered klah bark (or cinnamon) 
2 teaspoons citrus juice 
1-2 tablespoons butter or margarine 
Gently toss berries with sweetening and klah bark in a large bowl. Sprinkle citrus juice over mixture. Spoon berries into crust and dot with butter.

Bake at 375 o F for ten minutes. Remove foil. Bake for 8-12 minutes more, or until crust is golden. Serve hot.
