Raspberry-Rhubarb Slab Pie

I guess I better use up last years rhubarb before harvesting this years.  I just spent the weekend with all of my siblings and dad and mom and much of it with my sister-in-law and nieces and nephew.  When we gather, it's a safe bet there will be plenty of home baked goods.  These bars were my contribution, it's a new recipe, they were a HUGE hit!  The crust was very flaky. I made them with my dad in mind, he is partial to raspberries.  Funny, it took him quite a few bars to determine that in fact they were very good :).

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.
