Instructions for Making Lemon Bars

Baking these lemon bars is a joyful two-step process that fills your kitchen with a citrusy scent you’ll never forget. Here are the steps you’re going to follow:

1. Preheat Your Equipment:
   Set your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper, leaving a little overhang on the sides.
2. Combine Ingredients:
   In a bowl, mix flour, powdered sugar, and salt. Add cold butter cubes and use your fingers or a pastry cutter to blend until the texture resembles coarse crumbs.
3. Prepare Your Cooking Vessel:
   Press the crust mixture evenly into the bottom of your prepared pan. Prick lightly with a fork.
4. Assemble the Dish:
   Bake the crust for 20 minutes or until lightly golden. Meanwhile, whisk together eggs, sugar, lemon juice, lemon zest, cornstarch, and a bit of flour until smooth.
5. Cook to Perfection:
   Pour the lemon filling over the hot crust. Return to the oven and bake for another 20-25 minutes until the center is just set.
6. Finishing Touches:
   Let cool completely in the pan. Refrigerate for at least 2 hours before slicing.
7. Serve and Enjoy:
   Slice into squares and dust with powdered sugar just before serving.

Texture & Flavor Secrets

What makes these lemon bars unforgettable is the contrast. The crust is buttery and firm, giving way to a lush, zesty lemon layer that’s smooth and custard-like. The powdered sugar on top melts just slightly, adding a delicate sweetness to every tangy bite.

Cooking Tips & Tricks

Just a few extra things to help you ace it:

• Chill the bars for cleaner cuts and enhanced flavor.
• Use fresh lemons for both juice and zest to get that real citrus kick.
• Avoid aluminum pans—they can react with lemon juice and affect the taste.

What to Avoid

A few common mistakes that are easy to steer clear of:

• Overbaking: Can lead to a rubbery filling. Stop baking once the center is just set.
• Skipping the chill: Makes slicing messy and uneven.
• Using bottled juice only: It dulls the flavor. Always add some zest for balance.
