Raspberry-Rhubarb Slab Pie
3-1/4 c. flour
1 tsp. salt
1 c. butter
3/4 c. plus 1 to 2 T. milk
1 egg yolk
2 c. sugar
1/3 c. cornstarch
5 c. fresh or frozen unsweetened raspberries, thawed and drained
3 c. sliced fresh or frozen rhubarb, thawed and drained
Vanilla icing
1-1/4 c. confectioners' sugar
1/2 tsp. vanilla extract
5 to 6 tsp. milk
- 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 T. at a time, if necessary.
- Divide dough in half so that one portion is slightly larger than the other; wrap each in plastic wrap. Refrigerate for 1 hour or until easy to handle.
- Roll out larger portion of dough on lightly floured surface in to an 18 x 13-inch rectangle. Transfer to an ungreased 15 x 10 x 1-inch baking pan. Press onto the bottom and up the sides of pan; trim pastry to 1/2 inch above edges in pan.
- In a large bowl, combine sugar and cornstarch. Add raspberries and rhubarb; toss together to coat. Spoon into pastry.
- Roll out remaining dough; place over filling. Fold bottom pastry over edge of top pastry; seal with a fork. Prick top with a fork.
- Bake at 375° for 40-50 minutes or until golden brown. Cool completely on a wire rack.
- For icing, combine confectioners' sugar, vanilla and enough milk to achieve a drizzling consistency; drizzle over pie. Cut pie into 24 squares.
