Recipe Guide

What gives the lemon bars their tangy flavor?

Freshly squeezed lemon juice and finely grated lemon zest provide a bright, tangy flavor that defines the bars.

How can I achieve a buttery shortbread crust?

Cold, cubed unsalted butter cut into the flour and sugar mixture creates a crumbly texture that bakes into a rich, golden crust.

Why is the filling poured over the hot crust?

Pouring the filling onto the warm crust helps it set properly and melds the layers, ensuring a smooth, firm texture after baking.

Can these bars be made ahead of time?

Yes, chilling the bars before slicing helps achieve cleaner cuts and allows flavors to mellow and develop further.

Any suggestions for serving these lemon bars?

They pair wonderfully with a cup of Earl Grey tea or a glass of chilled Moscato, enhancing their fresh citrus notes.
