I made this pie for my husband's birthday last night (for the Montrealers, blueberries are on sale for $1.09/pint at Metro this week!) The pie crust is based on Gourmet's "Pate Brise".

Combine flour and salt, then cut in butter and shortening with pastry knife until it resembles course meal. (I cheat sometimes and use food processor on "pulse" only for this step). Add water and combine gently - add just enough water to make the dough hold when pressed together - too much water will make dough tough). Form into two patties, wrap in plastic wrap and refrigerate at least one hour.

Filling (for deep dish): Combine all ingredients except butter.

Roll one piece of dough to about 3 inches wider (diameter) than pie plate. Place into ungreased pie plate. Pour in filling. Place dots of butter on top of filling. Roll second piece of dough, place on top of filling, and tuck ends under bottom crust overhang. Trim decoratively and make decorative steam vents in top dough. Brush with milk or water and sprinkle with additional sugar.

Bake at 425 for 20 minutes, then turn oven down to 375 and bake an additional 30-40 minutes, until filling is bubbling and pie crust is brown. (Bake on lowest rack in oven so that top does not brown too quickly).
