Lemony Blueberry Bars: A Sweet and Zesty Delight

Ingredients

• Crust:
• 1 ½ cups of versatile all-purpose flour
• ½ cup of finely ground almond flour
• A pinch of salt for flavor
• Sweetness from ½ cup of white sugar
• 4 tablespoons of unsalted butter, softened
• 4 tablespoons of butter-flavored shortening for texture
• A hint of almond essence
• Filling:
• 2 cups of granulated white sugar
• 1 cup of sifted all-purpose flour for consistency
• 1 cup of freshly squeezed lemon juice for a zesty kick
• A touch of sweetness with ¼ cup of honey
• 6 large eggs, separated and at room temperature
• 2 ½ tablespoons of lemon zest for a burst of flavor
• A dash of baking soda
• 1 ½ cups of fresh blueberries to complement
• Meringue:
• 2 large egg whites for a fluffy texture
• ½ cup of white sugar for a sweet finish
• ¼ teaspoon of cream of tartar for stability
• A pinch of fine salt for balance and depth of flavor

Step 1

Begin by mixing together flour, almond flour, and salt in a mixing bowl to create the crust mixture.

Step 2

In a separate bowl, blend sugar, butter, shortening, and almond extract using a stand mixer with a paddle attachment until the mixture is light and slightly fluffy. Add the dry ingredients slowly on low speed just until combined, taking care not to overmix.

Step 3

Once the dough is ready, press it into a 9x13-inch glass baking dish with floured hands. Create a 1/2-inch edge around the sides to prevent the filling from sticking to the dish. Place the dish in the refrigerator and let it chill for at least 30 minutes.

Step 4

Preheat your oven to 350 degrees F (175 degrees C).

Step 5

Retrieve the crust from the refrigerator and bake it on the center rack of the preheated oven until the edges turn golden and the center is a pale golden color, which should take around 45 to 60 minutes. Allow the crust to cool completely on a wire rack for about 30 minutes, then reduce the oven heat to 300 degrees F (150 degrees C).

Step 6

While the crust is cooling, prepare the filling by combining sugar, flour, lemon juice, honey, egg yolks, egg whites, lemon zest, and baking soda in a bowl. Gently mix the ingredients together without overmixing to maintain the filling's texture. Save two egg whites for the meringue topping.

Step 7

Spread a layer of blueberries over the cooled crust and pour the prepared filling on top.

Step 8

Bake the bars in the 300 degrees F (150 degrees C) oven until the filling sets, which should take about 40 to 50 minutes. Remove from the oven and let it cool to room temperature on a wire rack for approximately 30 minutes.

Step 9

Adjust the oven rack to be about 6 inches from the broiler and preheat the broiler to high, or 525 degrees F (274 degrees C).

Step 10

To make the meringue, combine the reserved egg whites with additional egg whites, sugar, cream of tartar, and salt in a double boiler over simmering water. Whisk frequently until the sugar dissolves and the mixture is hot, about 2 to 3 minutes.

Step 11

Take the egg white mixture off the heat and beat it with an electric mixer until soft peaks form. Increase the speed to high and beat until stiff, but still spreadable, peaks appear. Spread and swirl the meringue over the cooled blueberry bars.

Step 12

Place the bars under the preheated broiler until the meringue turns evenly toasted and golden brown, usually around 30 to 60 seconds. Keep a close eye on them during this step.

Step 13

Finally, cut the bars into squares or triangles, then refrigerate them for about 3 hours until fully chilled. Enjoy the delightful and flavorful blueberry bars!
