I called this recipe key lime pie, but I have to confess that I do not use key limes. I used them the first time I made it, but key limes are so tiny it took a lot more time and effort to get enough juice, so I decided to use regular limes. We could not tell a difference, but we didn’t have a side by side comparison. If anyone feels there is a difference please let me know in the comment section below. I would be happy to hear your reasons! You might even convince me it is worth the effort, but for now I will use regular limes, just because it is easier and we think it tastes great. This pie is simple to make and is a wonderful fresh dessert. A small slice is usually all I need for a serving, as it is very rich.
