LEMON LIME BARS

Steps:

• Preheat oven to 350 degrees F.
• Grease a 13x9x2-inch baking pan. Line pan with parchment, pressing the paper onto the bottom and up the sides of the pan; set aside. In a large bowl combine the 2 cups flour, the 1/2 cup powdered sugar, the cornstarch and salt. Using a pastry blender, cut in butter until mixture resembles coarse crumbs (mixture will look dry). Press firmly into bottom of prepared pan. Bake 15 minutes (crust will still look dry).
• Meanwhile, in a medium mixing bowl whisk together the eggs, granulated sugar, half-and-half and 3 tablespoons flour; divide in two bowls. In one bowl add lemon peel and lemon juice; in the other bowl lime peel, lime juice and green food coloring into other half. Pour the lemon filling over hot crust; bake 10 to 12 minutes or until set. Carefully pour lime filling over lemon filling; bake 10 to 12 minutes more or until set. Cool completely in pan on a wire rack.
• Use paper to lift uncut bars from pan. Cut into bars. Sift over powdered sugar. Top with lemon and lime peel, if desired. Refrigerate to store. Makes 32 bars.
