Ingredients and Measurements

This recipe for homemade lemon bars yields approximately 16 squares. Accurate measurements are crucial for achieving the perfect balance of sweet, tart, and buttery goodness in your lemon bars. We’ll break down the ingredients into two parts: the crust and the lemon filling.

For the Crust:

The crust is the foundation of these delectable lemon bars, providing a delightful contrast to the tangy filling. We’ll be using a classic shortbread-style crust, known for its buttery crumbly texture. Ensure your butter is cold, straight from the refrigerator. This helps prevent the crust from becoming tough. Use a pastry blender or your fingers to cut the butter into the flour until it resembles coarse crumbs. Overmixing will develop the gluten in the flour, resulting in a tough crust.

• 1 ½ cups (190g) all-purpose flour: Use a good quality all-purpose flour for the best results. Avoid using self-rising flour, as it will alter the texture and taste of the crust. Spoon the flour into your measuring cup and level it off with a straight edge. Don’t scoop directly from the bag.
• ½ cup (113g) unsalted butter, cold and cut into cubes: Cold butter is vital for a flaky crust. If your butter is too soft, chill it in the refrigerator for 30 minutes before proceeding. Using unsalted butter allows you to control the salt level in your recipe.
• ¼ cup (50g) powdered sugar: This provides sweetness and tenderness to the crust. Ensure it’s finely powdered for even distribution.
• Pinch of salt: A pinch of salt enhances the flavors of the other ingredients, balancing the sweetness and adding depth.

For the Lemon Filling:

The lemon filling is the star of the show! The balance of sweetness and tartness is key. We’ll use fresh lemon juice for the most vibrant flavor, but you can substitute with high-quality bottled lemon juice in a pinch. Make sure to zest the lemons before juicing them to maximize the lemon flavor and aroma. The eggs bind the filling and add richness. Use large eggs for consistency.

• 1 ½ cups (300g) granulated sugar: This provides the sweetness for the filling. Granulated sugar dissolves well and contributes to a smooth texture.
• ¼ cup (60ml) fresh lemon juice: Freshly squeezed lemon juice is preferable for the best flavor. Strain the juice to remove any seeds or pulp. Adjust the amount according to your preference for tartness.
• 1 tablespoon lemon zest: Freshly grated lemon zest adds a bright, aromatic flavor to the filling. Avoid using pre-zested lemon peel as it often has a less intense flavor.
• 4 large eggs: The eggs bind the filling and contribute to its creamy texture. Ensure they are at room temperature for even mixing and better incorporation into the batter.
• ¼ cup (60ml) all-purpose flour: The flour helps to thicken the lemon filling, preventing it from becoming too runny.
• ⅛ teaspoon salt: Balances the sweetness and enhances overall flavor.
• (Optional) 1 tablespoon butter, melted: Adding melted butter adds richness and a subtle buttery flavor to the lemon filling.

Important Note: Always measure your ingredients accurately, using the correct measuring tools. Using a kitchen scale for weighing ingredients is highly recommended for precise results, particularly for the flour and butter.

Crust Preparation

The crust is the foundation of a perfect lemon bar, providing a delightful contrast to the tangy lemon filling. A well-made crust should be buttery, slightly crumbly, and not overly sweet. This recipe focuses on achieving that perfect balance.

We’ll begin by combining 1 ½ cups (190g) of all-purpose flour with ½ teaspoon of salt in a large bowl. Using a whisk ensures the salt is evenly distributed throughout the flour, preventing pockets of saltiness in the final crust. This is a crucial step for achieving a consistently flavorful crust.

Next, add 1 cup (2 sticks, 227g) of unsalted butter, which should be cold and cut into small cubes. Cold butter is essential for creating a flaky crust. The cold fat prevents the gluten in the flour from developing too much, resulting in a tender, rather than tough, crust. Using a pastry blender or your fingertips, cut the butter into the flour until the mixture resembles coarse crumbs. Work quickly to avoid warming the butter.

Now, we incorporate the sweetness. Add ½ cup (100g) of granulated sugar to the crumbly mixture. Avoid overmixing at this stage; simply combine the sugar with the flour and butter until it’s evenly distributed. Overmixing will develop the gluten and lead to a tough crust. Gentle incorporation is key.

Once the sugar is incorporated, gradually add 2-4 tablespoons of ice water, one tablespoon at a time, mixing lightly after each addition. The amount of water needed will depend on the humidity and the type of flour used. The dough should come together just enough to form a ball; it shouldn’t be sticky. If it’s too dry, add another tablespoon of ice water; if it’s too wet, add a tablespoon of flour.

Once the dough has formed a cohesive ball, flatten it into a disc, wrap it tightly in plastic wrap, and refrigerate it for at least 30 minutes. Refrigerating the dough allows the gluten to relax and the butter to firm up, which prevents shrinkage and ensures a beautifully even crust during baking. Chilling also helps to prevent the crust from becoming overly browned during baking.

After chilling, preheat your oven to 350°F (175°C). On a lightly floured surface, roll out the dough to a 9×13 inch rectangle. Ensure the dough is evenly rolled out to avoid uneven baking and a crust that’s too thick in some areas and thin in others. Gently transfer the dough to a 9×13 inch baking pan.

Use your fingers to press the dough evenly into the bottom and up the sides of the pan. Prick the bottom of the crust with a fork several times to prevent air bubbles from forming during baking. This ensures an even bake and prevents the crust from puffing up.

Bake the crust for 15-20 minutes, or until lightly golden brown. Keep a close eye on the crust as ovens vary, and overbaking will result in a dry and hard crust. Once baked, let the crust cool completely before adding the lemon filling.

Lemon Filling Preparation

Creating the perfect lemon filling is crucial for achieving delightful homemade lemon bars. This section details the process, offering tips for a smooth, tangy, and intensely flavorful result. We’ll be making a classic custard-style filling, known for its creamy texture and bright lemon taste.

Ingredients:

• 1 ½ cups granulated sugar
• 1/4 cup cornstarch
• 1/4 teaspoon salt
• 1 ½ cups freshly squeezed lemon juice (approximately 6-8 large lemons)
• 4 large eggs
• 4 tablespoons (1/2 stick) unsalted butter, melted and cooled slightly
• 1 tablespoon lemon zest (from about 2 lemons)

Instructions:

Begin by whisking together the sugar and cornstarch in a medium-sized heatproof bowl. This ensures that there are no lumps of cornstarch which can lead to a grainy texture in your final filling. Thoroughly whisk until completely smooth.

Next, gradually whisk in the lemon juice. This should be done slowly to avoid clumping. Ensure there are no lumps before proceeding. A whisk is ideal for this; a rotary whisk will help you achieve a completely smooth mixture.

In a separate bowl, whisk together the eggs until they are slightly frothy. This helps to incorporate air and creates a lighter filling. Avoid over-whisking, as this can make the eggs too stiff.

Gradually whisk the egg mixture into the lemon juice and sugar mixture. Continue whisking constantly to prevent the eggs from scrambling. The mixture will become slightly thicker as you whisk.

Stir in the melted butter and lemon zest. The melted butter adds richness and helps to create a smoother, more luxurious texture. The lemon zest enhances the bright, citrusy notes of the filling. Make sure the butter is only slightly warm to prevent the eggs from cooking prematurely.

Pour the lemon filling into the prepared crust. The crust should be pre-baked to prevent a soggy bottom. Spread the filling evenly across the crust ensuring it reaches all corners.

Bake the lemon bars according to the recipe instructions. Keep a close eye on the filling during baking; it should set to a firm but not rubbery consistency. Overbaking can lead to a dry and cracked filling.

Professional Tip: For an extra vibrant color and intense lemon flavor, use freshly squeezed lemon juice. Bottled lemon juice often lacks the acidity and aromatic compounds of fresh juice. Also, straining the lemon juice through a fine-mesh sieve will remove any seeds or pulp, resulting in a smoother filling.

Important Note: Allow the lemon bars to cool completely before cutting and serving. This allows the filling to set properly and prevents it from becoming messy or falling apart.

Baking Instructions

Preheat your oven to 350°F (175°C). This is crucial for ensuring the crust bakes evenly and the filling sets properly. Using a preheated oven is non-negotiable for optimal results.

Grease and flour a 9×13 inch baking pan. This prevents sticking and ensures easy removal of your finished lemon bars. You can use baking spray or rub the pan with butter or shortening, then dust generously with all-purpose flour. Tap out any excess flour. Properly preparing your pan is key to preventing a messy cleanup and ensuring your bars release easily.

In a medium bowl, whisk together 1 ½ cups (190g) all-purpose flour, ½ cup (100g) powdered sugar, and ¼ teaspoon of salt. Ensure all ingredients are thoroughly combined to prevent pockets of flour or sugar in your crust. Do not overmix the dry ingredients; this can lead to a tough crust.

Cut in ½ cup (113g) cold unsalted butter, using a pastry blender or your fingers, until the mixture resembles coarse crumbs. Work quickly to prevent the butter from melting. The colder the butter, the flakier your crust will be. Cold butter is essential for a tender and crumbly crust. If the butter is too soft, chill the mixture for 15-20 minutes before proceeding.

Press the crumb mixture evenly into the bottom of the prepared pan. Use the bottom of a measuring cup or your fingers to create an even layer. Ensure the crust is evenly distributed to prevent uneven baking.

Bake the crust for 15-20 minutes, or until lightly golden brown. Keep a close eye on it during the last few minutes to prevent burning. Overbaking the crust will result in a dry and hard texture.

While the crust is baking, prepare the lemon filling. In a medium bowl, whisk together 1 ¾ cups (350g) granulated sugar, ⅓ cup (60ml) fresh lemon juice (about 3 large lemons), ¼ cup (60ml) all-purpose flour, ¼ teaspoon salt, and 4 large eggs. Whisk vigorously until the mixture is smooth and free of lumps.

Carefully pour the lemon filling over the hot, baked crust. Avoid pouring the mixture onto a cold crust as it might result in uneven setting.

Bake for an additional 25-30 minutes, or until the filling is set and no longer jiggles in the center. The filling should be set but still slightly soft to the touch. Overbaking will result in a dry filling. The edges may start to brown slightly.

Let the lemon bars cool completely in the pan before cutting. This is crucial for preventing the bars from crumbling. Allowing them to cool completely will ensure they hold their shape and are easy to cut. Once cooled, cut into squares and dust with powdered sugar, if desired.

Store leftover lemon bars in an airtight container in the refrigerator for up to 3 days. Refrigeration will help maintain the freshness and prevent them from drying out.

Cooling and Setting

The cooling and setting process is crucial for achieving the perfect texture in your homemade lemon bars. A rushed cooling process can lead to a crumbly crust or a wobbly lemon filling, compromising both the presentation and the enjoyment of your delicious treats. Therefore, patience and attention to detail are key during this stage.

Once the lemon bars are removed from the oven, the baking dish will be extremely hot. Avoid touching the pan directly; use oven mitts or a hot pad to protect yourself from burns. Let the lemon bars cool completely in the pan on a wire rack for at least 30 minutes. This allows the initial heat to dissipate and prevents the bars from becoming soggy from residual moisture.

After the initial 30-minute cool-down, you’ll notice that the filling is still quite soft. This is expected. Do not attempt to cut or serve the lemon bars at this stage. Instead, continue to let them cool completely in the pan at room temperature for another 1-2 hours. The longer you let them cool, the firmer the filling will become, resulting in perfectly cut, clean bars.

The environment plays a significant role in the cooling process. Avoid placing the lemon bars in a drafty area, as this can cause uneven cooling and potentially crack the crust. A stable, room-temperature environment is ideal. If your kitchen is particularly warm, you might consider slightly reducing the oven temperature to 325°F (160°C) during the last 5-10 minutes of baking to prevent excessive browning and ensure more even cooling.

Once the 1-2 hour room temperature cooling period is complete, transfer the entire baking dish to the refrigerator. This is essential for achieving the final set of the lemon filling. Refrigerate the lemon bars for at least 4 hours, or preferably overnight. This extended refrigeration period allows the filling to fully solidify and develop its characteristic tangy-sweet flavor profile.

After refrigeration, you’ll find the bars are firm enough to be cut easily. Use a sharp knife, preferably a serrated one, to cleanly cut the bars into even squares. Wipe the knife blade clean between each cut to prevent sticking and ensure neat, perfectly shaped lemon bars. If the knife sticks, briefly running it under hot water can help.

Finally, before serving, allow the lemon bars to come to room temperature for about 15-20 minutes. This will allow the flavors to fully meld and enhance the overall taste experience. Serving slightly chilled lemon bars will offer the best balance of creamy filling and crisp crust.

By following these cooling and setting instructions meticulously, you will ensure your homemade lemon bars are not only delicious but also beautifully presented and of the highest quality. Enjoy!

Cutting and Serving

Cutting lemon bars correctly is crucial for achieving neat, evenly sized pieces that are easy to serve and visually appealing. The sharpness of your knife and the temperature of the bars will significantly impact the outcome. Always use a very sharp knife; a dull knife will crush the delicate crust and make for ragged edges.

Before you begin cutting, ensure your lemon bars are completely cool. Cutting warm bars will result in crumbling and uneven pieces. Allow them to cool completely at room temperature, ideally for at least 2-3 hours, or even better, overnight in the refrigerator. This allows the bars to firm up, making them much easier to cut cleanly.

For precise cutting, use a ruler and a sharp knife. Measure the dimensions of your baking pan. A standard 9×13 inch pan will yield approximately 24 bars if cut into 2-inch squares. However, you can adjust the size of your squares to your preference; smaller squares are ideal for parties, while larger ones are perfect for individual servings. Mark the pan lightly with a toothpick or the tip of your knife to guide your cuts.

Begin by cutting the lemon bars lengthwise, making the first set of cuts parallel to the longest side of the pan. Make firm, straight cuts, going all the way through the bars. Avoid sawing back and forth, as this will only damage the crust and filling. A single, confident movement is best.

Once the lengthwise cuts are complete, rotate the pan 90 degrees and repeat the process for the width. This will create a grid pattern of perfectly sized lemon bars. If your knife becomes sticky, wipe it clean with a damp paper towel between cuts. This will prevent the lemon filling from sticking to the blade and ensure clean, precise cuts.

For even easier cutting, consider using a pastry cutter or pizza cutter. These tools can often make cleaner cuts, especially when dealing with a very firm bar. However, a sharp chef’s knife remains the most versatile option.

Once cut, carefully lift the lemon bars from the pan using a spatula. Gently transfer them to a serving plate, arranging them neatly. Dusting the bars lightly with powdered sugar before serving adds a touch of elegance and enhances the visual appeal.

Serving suggestions: Lemon bars are best served at room temperature or slightly chilled. They pair beautifully with a dollop of whipped cream or a scoop of vanilla ice cream. They also make a delightful addition to afternoon tea or a summer picnic. Remember to store leftover lemon bars in an airtight container in the refrigerator for up to 3-4 days.

Important Note: The longer the lemon bars cool, the easier they will be to cut. Patience is key to achieving perfectly cut and served lemon bars. Enjoy!
