This was fabulous!!
I almost went to the grocery store to buy frozen raspberries for this recipe (the original recipe calls for raspberries), but at the last minute I realized, "What are you thinking??!! You have an abundance of strawberries in the garden, so why not substitute them?!" My commitment to eating what I can grow saved the day! I wasn't sure how the strawberries would work as a substitute, but they worked wonderfully. I loved the combination of the strawberries and rhubarb with buttery crust. The glazed topping added the perfect touch.
This was the first I had used butter in a pastry crust (had always used shortening before, but am determined to use butter or lard from now on). I still need to perfect my pastry skills when it comes to working with butter, but I was able to get the dough rolled out into a large sheet, so I was pleased! I can't wait to make this again when raspberries are in season. And, I just bought a rhubarb plant, so next year when I make it, I'll be able to use rhubarb from my garden!
3 1/4 c. all-purpose flour
1 t. salt
1 c. butter
3/4 c. plus 1-2 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*
1 1/4 c. confectioners' sugar
1/2 t. vanilla extract
5-6 t. milk
In a large bowl, combine flour and salt; cut in butter until crumbly. Whisk 3/4 c. milk and egg yolk; gradually add to flour mixture, tossing with a fork until dough forms a ball. Add additional milk, 1T. 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 between two large sheets of lightly-floured waxed paper into an 18x13" rectangle. Transfer to an ungreased 15x10x1" baking pan. Press onto the bottom and up the sides of pan; trim pastry to 1/2" above edges of 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 degrees for 45-55 min. 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 squares.
*Note: If using frozen rhubarb, measure rhubarb while still frozen, then thaw completely. Drain in a colander, but do not press liquid out.
