Start with fresh Key limes, Florida ones are best. You can substitute for regular lime if you have to. In any case, use fresh lime juice.
We used Graham crackers for the crust. We used a meringue topping to top the pie.
Once cooled to room temperature, the pie can stay in the fridge loosely covered for up to two days.
