Lemon Lime Blueberry Squares Recipes

LEMON-BLUEBERRY BARS

Steps:

• Heat oven to 325 degrees and line a 9-inch square baking dish with parchment paper so it hangs over the edges on all sides by a few inches. (You may need to use two pieces of parchment.)
• Make the crust: In the bowl of a food processor, pulse to combine the flour, confectioners' sugar, lemon zest and salt. Add butter and pulse until a crumbly dough forms, about 10 seconds. (Or mix dry ingredients in a bowl and use pastry cutter to cut in butter, clumping the mixture together in your hands until it holds together.) Press dough into prepared pan. Bake until light golden, 25 to 35 minutes.
• As crust bakes, make the curd: In a medium pot, whisk together the granulated sugar, lemon juice, egg yolks, whole eggs, cornstarch and fine sea salt until well combined. Place over medium heat and stir with a heatproof rubber spatula (or wooden spoon), making sure to scrape around the sides and edges of the pot, until mixture is simmering and thickened, 5 to 10 minutes.
• Bring mixture to a boil and let cook for about 30 seconds, but no longer than 1 minute. Immediately strain through a fine mesh sieve into a bowl. Stir in butter, lemon zest and lime zest, and stir until butter melts. Stir in blueberries.
• Pour mixture over crust, then stir to evenly distribute berries. Return to oven, and bake until blueberries begin to burst and curd starts to turn golden around the edges, 33 to 45 minutes. Transfer to a wire rack to cool to room temperature. Chill in the refrigerator until thoroughly cold before cutting, at least 3 hours. Dust lightly with confectioners' sugar right before serving.

Steps:

• Preheat oven to 350 degrees F (175 degrees C). Spray a 9x13-inch baking dish with cooking spray.
• Process 2 cups flour, butter, and 1/2 cup confectioners' sugar in a food processor until mixture resembles coarse crumbs; press into the prepared baking dish.
• Bake in the preheated oven until the edges of the crust are golden brown, 18 to 22 minutes. Cool crust to room temperature.
• Beat white sugar, eggs, 1/4 cup flour, lemon juice, baking powder, and lemon zest together in a bowl using an electric mixer until light and fluffy; pour onto the cooled crust.
• Bake in the oven until custard is set, 25 to 28 minutes. Cool lemon squares completely; dust the top with more confectioners' sugar.

LEMON-LIME BLUEBERRY SQUARES

Steps:

• Make crust:
• Preheat oven to 375°F. Line a buttered 8-inch square glass baking dish with 2 (18- by 6-inch) sheets of foil, overlapping them in opposite directions so that there is overhang on all 4 sides.
• Pulse together flour, cornmeal, confectioners sugar, salt, and butter in a food processor until mixture resembles coarse meal. Press onto bottom of baking dish and 1 inch up sides. Bake in middle of oven until golden brown, about 20 minutes.
• Make filling while crust bakes:
• Whisk together eggs, sugar, flour, and zests. Whisk in juices, milk, and a pinch of salt. Toss blueberries with jam in another bowl.
• Whisk egg mixture and immediately pour into hot crust, then bake until just set, about 17 minutes. Gently spoon berries evenly over top and bake 2 minutes more. Transfer baking dish to a rack and cool.
• Chill, covered, overnight (8 hours). Use foil to lift dessert out of dish, then cut into squares.
