8 Tbs. reduced-calorie margarine, stick, chilled and cut up
8 Tbs. fat-free margarine, tub, chilled
5 Tbs. cold water
5 cups blueberries (fresh or frozen and thawed)
1/4 cup cornstarch
2 tsp. lemon zest
1 tsp. vanilla extract
1 large egg white
Instructions
Preheat oven to 375 degrees F
In a large bowl, combine flour, 1 tsp. sugar, salt and both margarines
Mix with a fork (or both hands) until mixture resembles coarse meal
Add 4 Tbs. of water and mix until dough can be formed into a ball, adding more water if necessary
Transfer dough to a lightly floured surface and divide into two equal portions
Roll each portion into a 12-inch round
Press one round into the bottom and up the sides of a 9-inch pie plate, allowing dough to hang over sides; set aside
In a large bowl, combine blueberries, 1/3 cup of sugar, cornstarch, zest and vanilla extract
Toss to combine
Pour mixture into pie crust
Place second pie crust on top of blueberries and pinch two crusts together to form a seal. Using two fingers, pinch around edges to form a decorative rim.
Whisk together egg white and 1 tablespoon water
Brush mixture over surface of pie
Sprinkle with remaining teaspoon sugar
Prick top crust all over with a fork or sharp knife to allow steam to escape during cooking
Transfer pie to a baking sheet and bake until crust is golden and filling is bubbling out of holes, about 1 hour and 15 minutes
Cool on a rack, about 10 minutes, before slicing into 10 pieces
