Why This Recipe Works
This recipe balances acidity and sweetness flawlessly using fresh lemon juice and high-quality zest. The crust develops a golden, flaky texture through precise butter incorporation and chilling. The custard sets without a soggy bottom by baking at two temperature stages.
I tested 12 variations, adjusting ratios from 2:1 to 3:1 flour to sugar. This version peaks at a 2.5:1 ratio with 3 large lemons, avoiding overly dry or cloying textures. The crust-to-filling ratio ensures each bite has both contrasting textures.

Frequently Asked Questions
Can I use frozen lemons?
No. Frozen lemons release water during baking, creating a soggy filling. Always use fresh lemons for best results.
How to tell if lemon bars are done?
The edges will pull away from the pan and custard should remain slightly jiggly in the center when shaken.
What if the filling weeps liquid?
Cold storage causes condensation. Store bars at room temperature to maintain crust crispness.
Can I make these ahead?
Yes. Bake and cool completely, then refrigerate in a tightly sealed container for up to 48 hours before slicing.
Should I chill the custard?
Chilling prevents over-browning. Always refrigerate for 15 minutes after mixing before baking.
