Variations and Tips

While traditional Key Lime Pie is hard to beat, there are several variations you can explore. Some bakers like to add a pinch of salt to the crust for extra flavor, while others experiment with different crust bases like digestive biscuits or vanilla wafers.

If you're unable to find fresh Key limes, Persian limes can be used as a substitute, though purists argue that the flavor is not quite the same. Additionally, you might consider adding a touch of vanilla extract to the filling for an extra layer of depth.
