Fresh key lime juice is preferred for flavoring marinades, making limeade, and garnishing drinks and plates due to its tantalizing bouquet and unique flavor. The juice is used for syrups and, of course, key lime pie. Most commercially available key lime pies these days are made from the frozen concentrate of the Persian lime, not the key lime. If you’ve never had a true key lime pie, it’s worth seeking out.
