Blueberry Pie

Blueberry Pie
Crust for 2 - 10" pies
4 cups flour
2 cups shortening
2 tsp. salt
1 tsp. vinegar
1/2 cup cold water
1 egg, well beaten

2-1/2 to 3 cups fresh or frozen blueberries
3/4 to 1 cup sugar
3 Tbsp. flour
2 Tbsp. lemon juice or sherry wine

Sift the dry ingredients together and cut in shortening. Mix water, vinegar, and well beaten egg. Add to the dry ingredients all at one time. Divide into four parts, ready to roll out.
Mix ingredients for filling together and place in bottom crust. Seal top crust, providing air vents. Bake at 450 degrees for 10-15 minutes. Reduce heat to 375 degrees and bake until the fruit is bubbly (25-30 minutes).
