Blueberry Bars

• 2 12 cups flour, sifted
• 12 cup sugar
• 12 teaspoon baking powder
• 1 cup butter, softened
• 2 cups blueberries
• 4 tablespoons sugar
• 1 tablespoon lemon juice
• 1 tablespoon lemon peel, grated
• 2 tablespoons cornstarch
• 14 teaspoon salt

1. To make the crust: sift the dry ingredients (flour - baking soda) into a mixing bowl.
2. Using a fork or two knives mix the butter until the mixture resembles fine crumbs.
3. With your hands press mixture into a dough.
4. Roll dough out on a floured board to fit a 12-x 16 inch pan (I used a roasting pan), reserving 1/2 cup of the dough to use for topping.
5. Put crust in pan, patch it if need be.
6. With your fingers, form a ridge around the edge of the dough so the filling will not run over during baking.
7. To prepare filling: pour the blueberries into a mixing bowl, mashing a bit to produce juice.
8. Stir in the remainder of the ingredients (sugar - salt).
9. Spread filling over crust in pan.
10. Roll out reserved dough on a floured board to 1/8 to 1/4 inch thickness.
11. Cut into strips and place in a lattice pattern on the filling -- or crumble remainder over the filling.
12. Sprinkle with additional sugar if desired (these bars are not very sweet).
13. Bake in a pre-heated 375 degree oven for 25 - 30 minutes.
14. Cut into squares to serve.
