# Expert Tips:

01 -
  • That buttery shortbread crust melts in your mouth while the bright lime filling wakes up your taste buds in the most delightful way
  • They come together faster than youd think, and you can make them a day ahead so youre not rushing when guests arrive
02 -
  • Overbaking the filling makes it rubbery and sad, so pull them out the moment the center no longer jiggles
  • These really do need that full hour in the fridge to set properly, or youll end up with a gooey mess when you try to cut them
03 -
  • Zest your limes before squeezing them—its nearly impossible to zest a squeezed lime half
  • Room temperature ingredients blend more smoothly, so take everything out about 30 minutes before you start
