"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. —Jeanne Ambrose, Milwaukee, Wisconsin

Raspberry-Rhubarb Slab Pie Recipe

Prep: 30 min. + chilling Bake: 45 min. + cooling

Yield: 24 Servings

30 45 75

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 egg yolk
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

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.
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 18-in. x 13-in. rectangle. Transfer to an ungreased 15-in. x 10-in. x 1-in. baking pan. Press onto the bottom and up the sides of pan; trim pastry to edges of pan.
In a large bowl, combine sugar and cornstarch. Add raspberries and rhubarb; toss 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 45-55 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 squares. Yield: 2 dozen.

Editor's Note: If using frozen rhubarb, measure rhubarb while still frozen, then thaw completely. Drain in a colander, but do not press liquid out.

I made this today, but used strawberries on place of the rhubarb only because I didnt have any rhubarb. It is amazing and I'll make it again. Next time I want to try the rhubarb for the tang...
