Raspberry-Rhubarb Slab Pie

Ingredients

  • 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
  • 3 cups sliced fresh or frozen rhubarb, thawed and drained
  • VANILLA ICING:
  • 1-1/4 cups confectioners' sugar
  • 1/2 teaspoon vanilla extract
  • 5 to 6 teaspoons 2% milk

Directions

  • 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.

    Hi Donna, The recipe states to preheat the oven to 375 degrees. That would be your baking temp. for the pie.

    ust finished the book recipe box. By Viola Shipman. As I am reading the book this pie comes up at the beginning, and I am thinking. "Hmmmm I have made this, or something similar". When you get to the end in the credits Viola posts this recipe via the web adress and I am freaking out! This is the one I make!! First time commenting about it. Perfect as is!

    I prefer using Crisco instead of butter, just add 2T. extra, and use ice water instead of milk. Much flakier!

    Very good. I took it to a picnic and didn't get to bring any home. Definitely will make again..

    I made this with equal amounts of rhubarb and raspberries and a bit less sugar. My family and friends loved it!

    This was a great way to use the frozen raspberries and rhubarb that I had in the freezer. I am not the greatest pastry chef, so rolling out dough is not an easy job for me. But, I managed. I went one step further and used the food processor for the rhubarb to give it a more even consistency.

    But, I am confused as to why the oven temperature needs to be 375. In this day and age of well-insulated ovens and pans that are non-stick, I never need to use 375 and I put my oven at 350 for the allotted time and it was still slightly over-baked.

    Take it easy on the heat.

    Yummy.

    Our family loves both raspberries and rhubarb-the combination is outstanding. I do 1 1/2 times the recipe as I use a LG jelly roll pan. Outstanding dessert

    Great dessert for a crowd. I have also made it with strawberries as well. I also reduced berries by a cup and added a cup to the rhubarb. I will definitely make this again.

    One of only ways I will eat rhubarb. The only change that I make is I use the pie crust only on the bottom and substitute sugar cookie dough on top. It makes. Great different way of putting it together.
