Slab pie

A no-fuss summer party/picnic dessert. Makes an entire large pyrex dish of pie.

Ingredients

• 4 cups all-purpose flour
• 1 tablespoon sugar
• 2 teaspoons salt
• 1-3/4 cup cold shortening
• 1/2 cup cold water
• 1 large egg
• 1 tablespoon white vinegar
• FILLING:
  • 8 cups fresh or frozen blackberries
  • 2 cups sugar
  • 1/2 cup all-purpose flour
  • Half-and-half cream

Directions

1. In a large bowl, combine flour, sugar and salt; cut in shortening until mixture resembles coarse crumbs. In a bowl, combine water, egg and vinegar; stir into flour mixture just until moistened. Form into a roll. Cover and refrigerate for 1 hour.
2. On a floured surface, roll two-thirds of the dough into a 18x14-in. rectangle. Carefully place onto the bottom and up the sides of a 13x9-in. baking dish. Combine berries, sugar and flour; pour into crust. Use the remaining dough to make lattice strips; place over the filling. Brush pastry with cream.
