     1/4 ts Baking powder
       4 tb Butter
       1 lg Egg
 MMMMM---------------------BLUEBERRY FILLING--------------------------
       2 pt Blueberries
     3/4 c  Sugar
       3 tb Cornstarch
       3 tb Water
       1 tb Grated lemon zest
     3/4 c  Walnut pieces
            - toasted & coarsely chopped
 MMMMM--------------------WALNUT CRUMB TOPPING-------------------------
       4 tb Butter
     1/4 c  Sugar
     1/2 ts Cinnamon
     3/4 c  Unbleached all-purpose flour
     1/2 c  Walnuts, coarsely chopped
   MIXING THE PASTRY DOUGH: Stir together the dry ingredients in a bowl.
   Cut up and add the butter; toss gently to coat. Rub in the butter
   until the mixture looks sandy. Beat the egg and toss into the flour
   and butter mixture. Press the dough together, wrap and chill it.
   FORMING THE PIE SHELL: Lightly flour the work surface and dough. Roll
   the dough to a 14-inch diameter disk, 1/8-inch thick. Fit the dough
   into a 9-inch oven-proof glass pie pan and trim away all but 1/4-inch
   of the excess dough. Turn the excess dough under and flute the edge
   of the pie. Chill while preparing the filling.
   MIXING THE FILLING: Rinse and pick over the blueberries and drain
   them on a paper-towel-lined pan. Combine one third of the berries and
   the sugar in a saucepan and bring to a simmer over medium heat,
   stirring occasionally. Simmer the berries in the juices that
   accumulate about 5 minutes. Strain the juices into another pan. Pour
   the water into a small bowl and stir in the cornstarch to dissolve
   it. Return the blueberry juices to a boil and beat about one quarter
   of it into the dissolved cornstarch. Return the remaining juices to a
   boil and beat the cornstarch mixture into it. Return the juices to a
   boil, beating constantly, and allow to boil about 1 to 2 minutes,
   beating constantly. Stir in the remaining blueberries, the cooked
   berries, lemon zest and walnuts, and cool.
   MIXING THE CRUMB TOPPING: Cream the butter until soft, add the sugar
   and cream until soft and light. Beat in the cinnamon. Mix in the
   flour, then the walnuts. The mixture should fall into large, soft
   crumbs. Pour the filling into the prepared pan and smooth. Scatter
   over the crumbs and bake at 350F until the filling is set, the crumbs
   have colored and the crust is baked through, about 40 minutes. Cool
   on a rack. Makes one 9-inch pie.
