Blueberry Lemon Bars With Meringue Topping Recipes

BLUEBERRY-LEMON CRUMB BARS

Steps:

• Preheat oven to 400 degrees F (200 degrees C). Grease a 9x13 inch baking pan.
• Start by making the crust. In a medium bowl, stir together the 2 cups flour, 2 tablespoons white sugar, lemon zest and salt. Cut in the 1/2 cup butter until the mixture resembles coarse crumbs. Beat egg and vanilla together; stir into the crumb mixture until a dough forms. Press into the bottom of the prepared pan.
• Bake for 12 to 15 minutes in the preheated oven, until golden. Remove from oven and set aside to cool slightly.
• Sprinkle blueberries over the crust. Combine the 1/4 cup sugar and nutmeg; sprinkle over the blueberries. Make the topping: In a medium bowl, cream together the 5 tablespoons butter and brown sugar until smooth. Mix in the flour, so that the mixture is crumbly like streusel. Sprinkle over the blueberry layer.
• Bake for 20 to 25 minutes in the preheated oven, until browned. Cool and then dust with confectioners' sugar before cutting into bars.

BLUEBERRY LEMON BARS WITH MERINGUE TOPPING

Steps:

• Combine flour, almond flour, and salt for crust in a bowl.
• Combine sugar, butter, shortening, and almond extract in the bowl of a stand mixer fitted with the paddle attachment; beat until light and somewhat fluffy. Add dry ingredients on low speed until just mixed, about 1 minute; do not overmix.
• Drop dough into a 9x13-inch glass baking dish and flatten with floured hands, building up a 1/2-inch edge on the sides so the filling doesn't stick to the dish. Transfer to the refrigerator to chill for at least 30 minutes.
• Preheat the oven to 350 degrees F (175 degrees C).
• Remove crust from the refrigerator and bake on the center rack of the preheated oven until golden at the edges and pale golden in the center, 45 to 60 minutes. Remove from the oven and let sit on a wire rack until completely cool, about 30 minutes. Reduce oven heat to 300 degrees F (150 degrees C).
• While the crust is cooling, combine sugar, flour, lemon juice, honey, 6 egg yolks, 4 egg whites, lemon zest, and baking soda for filling in a bowl. Whisk briefly to combine, but don't overmix because we don't want to over-aerate the filling. Set aside 2 remaining egg whites for the meringue topping.
• Spread blueberries over the cooled crust, then pour filling over top.
• Bake in the 300 degrees F (150 degrees C) oven, checking frequently, until filling is set, 40 to 50 minutes. Remove from the oven, turn oven off, and let cool to room temperature on a wire rack, about 30 minutes.
• Set an oven rack about 6 inches from the heat source and preheat the oven's broiler to high, or 525 degrees F (274 degrees C).
• Combine 2 reserved egg whites from the filling with 2 egg whites, sugar, cream of tartar, and salt for meringue in the top of a double boiler over simmering water. Whisk frequently, scraping down the sides with a rubber spatula to avoid scorching, until sugar has dissolved and mixture is hot, 2 to 3 minutes.
• Remove egg white mixture from the heat and beat with an electric mixer on medium speed until soft peaks form. Increase speed to high and beat until meringue holds stiff, but spreadable, peaks. Spread and swirl meringue on top of the cooled blueberry bars.
• Set the lemon bars under the preheated broiler until meringue is evenly toasted and golden brown, about 30 to 60 seconds; do not walk away.
• Cut into 24 squares or triangles and refrigerate until chilled, about 3 hours.

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.
