Note: This pie takes a little time to assemble, but all of the steps are easy. There is some cooling and chilling time in between layers though, so it isn't a fast pie. But it's also not difficult so don't be intimidated by the long recipe! Also, wait until it's completely cooled to slice into it, or the lemon layer will be runny. If you wait until it's cooled, or even chill it in the refrigerator, the filling will set up.
