Why These Lemon Squares Are the BEST
Before diving into the recipe, let’s talk about what makes a truly exceptional lemon square. It’s all about the balance of textures and flavors:
* **A Buttery, Tender Crust:** The foundation of any great lemon square is a shortbread crust that’s crisp yet tender, providing a sturdy base that doesn’t crumble into a mess. The buttery flavor should complement, not overpower, the lemon filling.
* **A Tangy, Creamy Filling:** The lemon filling should be intensely flavored with fresh lemon juice and zest, offering a vibrant tang that awakens the taste buds. It should be creamy, smooth, and set just enough to hold its shape without being rubbery.
* **Perfect Sweetness:** The sweetness should balance the tartness of the lemon, creating a harmonious flavor profile that’s both refreshing and satisfying.
* **Clean Cuts:** Achieving clean, neat cuts is a sign of a well-baked and well-chilled lemon square.
## The Ultimate Lemon Square Recipe
This recipe incorporates all the tips and tricks to guarantee lemon square success. We’ll break it down into two parts: the shortbread crust and the lemon filling.
**Yields:** 16-20 squares
**Prep Time:** 30 minutes
**Chill Time:** 30 minutes (crust), 2 hours (squares)
**Bake Time:** 30-35 minutes
Ingredients for the Shortbread Crust:
* 1 ½ cups (192g) all-purpose flour
* ½ cup (57g) powdered sugar
* ¾ cup (1 ½ sticks or 170g) unsalted butter, cold and cubed
* ¼ teaspoon salt
Ingredients for the Lemon Filling:
* 1 ½ cups (300g) granulated sugar
* ¼ cup (30g) all-purpose flour
* ½ teaspoon baking powder
* ¼ teaspoon salt
* 4 large eggs
* ⅔ cup (160ml) fresh lemon juice (from about 4-5 lemons)
* 2 tablespoons lemon zest (from about 2-3 lemons)
* Powdered sugar, for dusting (optional)
Equipment:
* 8×8 inch baking pan
* Parchment paper
* Mixing bowls
* Measuring cups and spoons
* Whisk
* Citrus zester
* Citrus juicer
Instructions:
**Part 1: Making the Shortbread Crust**
1. **Prepare the Pan:** Preheat oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper, leaving an overhang on two sides for easy removal. This is crucial for lifting the finished squares out cleanly.
2. **Combine Dry Ingredients:** In a medium bowl, whisk together the flour, powdered sugar, and salt. This ensures even distribution of the ingredients.
3. **Cut in the Butter:** Add the cold, cubed butter to the dry ingredients. Use a pastry blender or your fingertips to cut the butter into the flour mixture until it resembles coarse crumbs. The colder the butter, the better the texture of the crust. Avoid overworking the mixture.
4. **Press into the Pan:** Press the mixture firmly and evenly into the prepared baking pan. Use the bottom of a measuring cup or a flat-bottomed glass to ensure a smooth, compact crust. A well-compacted crust will prevent it from becoming soggy.
5. **Pre-Bake the Crust:** Bake the crust for 18-20 minutes, or until lightly golden brown around the edges. Keep a close eye on it to prevent burning. Let the crust cool slightly while you prepare the lemon filling. Leaving the oven on is fine.
**Part 2: Making the Lemon Filling**
1. **Whisk Dry Ingredients:** In a large bowl, whisk together the granulated sugar, flour, baking powder, and salt. The flour helps to stabilize the filling and prevent it from curdling.
2. **Add Wet Ingredients:** Add the eggs, lemon juice, and lemon zest to the dry ingredients. Whisk until well combined and smooth. Make sure there are no lumps.
3. **Pour over Crust:** Pour the lemon filling evenly over the pre-baked crust. Gently tap the pan on the counter to release any air bubbles.
4. **Bake the Squares:** Bake for 30-35 minutes, or until the filling is set and the edges are lightly golden brown. The center should be slightly jiggly but not liquid. Overbaking will result in a rubbery filling. If the crust starts to brown too quickly, tent the pan with foil.
5. **Cool Completely:** Remove the pan from the oven and let the lemon squares cool completely in the pan on a wire rack. This is crucial for the filling to set properly. Allowing it to cool gradually helps prevent cracking.
6. **Chill Before Cutting:** Once cooled, cover the pan with plastic wrap and refrigerate for at least 2 hours, or preferably overnight. Chilling makes it easier to cut the squares cleanly.
7. **Cut and Serve:** Using the parchment paper overhang, lift the lemon squares out of the pan. Cut into squares using a sharp knife. For clean cuts, wipe the knife clean between each slice. Dust with powdered sugar, if desired.
## Tips for Lemon Square Perfection
* **Use Fresh Lemon Juice and Zest:** Bottled lemon juice simply doesn’t compare to the bright, vibrant flavor of fresh lemon juice. Zest adds an extra layer of lemony goodness.
* **Don’t Overbake:** Overbaking is the enemy of a creamy lemon square filling. The filling should be set but still slightly jiggly in the center.
* **Chill Thoroughly:** Chilling the squares completely allows the filling to set properly and makes them much easier to cut.
* **Use a Sharp Knife:** A sharp knife is essential for clean, neat cuts. Wipe the knife clean between each slice.
* **Adjust Sweetness to Taste:** If you prefer a tarter lemon square, you can reduce the amount of sugar in the filling slightly. If you like it sweeter, add a bit more.
* **Zest Carefully:** When zesting lemons, avoid the white pith, which is bitter. Only zest the yellow part of the peel.
* **Line Your Pan:** Lining the baking pan with parchment paper makes it easy to lift the finished squares out of the pan without sticking.
* **Don’t Skip the Pre-Bake:** Pre-baking the crust prevents it from becoming soggy when the lemon filling is added.
* **Let the Crust Cool Slightly:** Letting the crust cool slightly before adding the filling helps to prevent the filling from seeping underneath.
* **Use a Good Quality Butter:** The flavor of the butter will shine through in the shortbread crust, so use a good quality butter for the best results.
## Variations on the Classic Lemon Square
While the classic lemon square is perfect as it is, there are plenty of ways to customize it to your liking.
* **Lavender Lemon Squares:** Add 1-2 teaspoons of dried lavender buds to the lemon filling for a floral twist.
* **Raspberry Lemon Squares:** Swirl raspberry jam into the lemon filling before baking.
* **Blueberry Lemon Squares:** Scatter fresh blueberries over the crust before pouring on the lemon filling.
* **Coconut Lemon Squares:** Add shredded coconut to the shortbread crust and/or the lemon filling.
* **Lime Squares:** Substitute lime juice and zest for the lemon juice and zest for a refreshing lime version.
* **Meyer Lemon Squares:** Meyer lemons are sweeter and less acidic than regular lemons, resulting in a milder, more delicate lemon square.
* **Gluten-Free Lemon Squares:** Use a gluten-free all-purpose flour blend for both the crust and the filling.
* **Vegan Lemon Squares:** Substitute the butter with vegan butter and use an egg replacer in the filling. There are several recipes available online for vegan lemon squares.
## Troubleshooting Common Lemon Square Problems
* **Soggy Crust:** This is usually caused by not pre-baking the crust or by the filling seeping underneath. Make sure to pre-bake the crust until lightly golden brown and let it cool slightly before adding the filling. Ensure your crust is well compacted before baking.
* **Rubbery Filling:** This is usually caused by overbaking. Bake the squares until the filling is set but still slightly jiggly in the center.
* **Cracked Filling:** This can be caused by cooling the squares too quickly or by temperature fluctuations. Let the squares cool completely in the pan on a wire rack and avoid placing them in a draft.
* **Filling Not Setting:** This can be caused by not using enough lemon juice or by not baking the squares long enough. Make sure to measure the lemon juice accurately and bake the squares until the filling is set.
* **Difficult to Cut:** This is usually caused by not chilling the squares thoroughly. Chill the squares for at least 2 hours before cutting.
## Serving and Storing Lemon Squares
Lemon squares are best served chilled or at room temperature. Dust with powdered sugar just before serving, if desired.
* **Storing:** Store lemon squares in an airtight container in the refrigerator for up to 5 days.
* **Freezing:** Lemon squares can be frozen for up to 2 months. Wrap them individually in plastic wrap and then place them in a freezer-safe container.
## The Final Verdict
With their bright, tangy flavor and creamy texture, these lemon squares are sure to be a hit. Follow these tips and tricks, and you’ll be baking the best lemon squares you’ve ever tasted. So, gather your ingredients, preheat your oven, and get ready to experience lemon square perfection! Enjoy!
