Bluegrass Pie

This is also known as Thoroughbred Pie, Winner's Circle Pie, Kentucky Oaks Pie, and Run for the Roses Pie. It is a hallmark of the Kentucky Derby.

Pie Crust
1 1/2 cups flour
1/2 teaspoon salt
1/2 teaspoon granulated sugar
8 tablespoons unsalted butter, very cold
2 tablespoons solid shortening, very cold
About 4 tablespoons ice water

Mix flour, salt and sugar. Cut butter into pieces. Cut in butter and shortening until mixture resembles flaky meal. Sprinkle in ice water. Work into a ball that cleans the sides of the mixing bowl. (To mix in a food processor, place dry ingredients in work bowl. Top with pieces of cold butter and shortening, and pulse until mealy. With machine running, pour in ice water all at once. When dough forms a ball that knocks around sides of the bowl, stop machine at once.)

Flatten dough into a disk. Wrap with plastic wrap and chill 30 minutes (or freeze).

Roll dough into a circle 3 to 4 inches wider than pie plate, set in the plate, and trim with scissors so dough extends 3/4 inch beyond the rim. Fold this overhand under so it is even with plate's rim and crimp into large flutes. Chill 30 minutes, while you prepare the filling.
