Fantastic. For one thing, the timing instructions were dead on for both the crust and final product, which is rare in a baking recipe. One more minute would have been too long.
The crust makes these lemon bars stand out. This crust has to be handled like a pie crust. If you follow the instructions and don't over work the dough, and very gently press it into the pan (I barely wet my fingers), you will get a delicious, flaky crust. Too much mixing or too firm of pressing will make it more dense.
I do not have a good zester, so I used only 1/4 tsp of zest and it was plenty lemony. Final note--I used organic eggs, which tend to have an orange color as eggs are actually supposed to.
