Notes

One can add powdered sugar and sliced lemon on top of each bar.
Use a glass or ceramic plan. Do not use metal, as the lemon bars will taste of metallic.
Always use fresh juice over store-bought. You will reap all the benefits of the lemon flavor.
The bars may seem wobbly and not fully set, even though the toothpick comes out clean, but they will continue to bake while cooling.
The chill time is extremely important for the bars to be completely set.
These can be gluten-free by replacing the all-purpose flour with gluten-free all purpose flour.
