Raspberry-Rhubarb Slab Pie

  Desserts

"Slab pie" is a pastry baked in a jelly-roll pan and cut in slabs like a bar cookie—or a pie bar, if you will. My grandfather was a professional baker and served pieces of slab pie to his customers back in the day. Here is my spin, featuring rhubarb and gorgeous red raspberries.

  • 3-1/4 cups all-purpose flour
  • 1 teaspoon salt
  • 1 cup butter
  • 3/4 cup plus 1 to 2 tablespoons 2% milk
  • 1 large egg yolk, room temperature
  • 2 cups sugar
  • 1/3 cup cornstarch
  • 5 cups fresh or frozen unsweetened raspberries, thawed and drained

  • VANILLA ICING:
  • 1-1/4 cups confectioners' sugar
  • 1/2 teaspoon vanilla extract
  • 5 to 6 teaspoons 2% milk

Instructions

  • 1. In a large bowl, combine flour and salt; cut in butter until crumbly. Whisk 3/4 cup milk and egg yolk; gradually add to flour mixture, tossing with a fork until dough forms a ball. Add additional milk, 1 tablespoon at a time, if necessary.
  • 2. Divide dough in 2 portions so that 1 is slightly larger than the other; cover each and refrigerate 1 hour or until easy to handle.
  • 3. Preheat oven to 375°. Roll out larger portion of dough between 2 large sheets of lightly floured waxed paper into an 18x13-in. rectangle. Transfer to an ungreased 15x10x1-in. baking pan. Press onto the bottom and up sides of pan; trim crust to edges of pan.
  • 4. In a large bowl, combine sugar and cornstarch. Add raspberries and rhubarb; toss to coat. Spoon into crust.
  • 5. Roll out remaining dough; place over filling. Fold bottom crust over edge of top crust; seal with a fork. Prick top with a fork.
  • 6. Bake until golden brown, 45-55 minutes. Cool completely on a wire rack.
  • 7. For icing, combine confectioners' sugar, vanilla and enough milk to achieve a drizzling consistency; drizzle over pie. Cut pie into squares.
