Bright and zesty Key Lime recipes
It’s safe to say that I’m mildly obsessed with Key Limes (and citrus desserts in general). These sweet and tart balls of delicious citrus are one of my favorite ingredients. As summer rolls in, you best believe I’m raiding my local farmers’ markets for a bounty of fresh key limes. There are so many ways to use them in all kinds of recipes, baking and beyond. Below I share everything you want to know about Key Limes. Also, I’ve included 10 of my favorite key lime recipes to inspire your own obsession.
Limes vs. Key Limes
So what is the difference between a lime and a key lime? True limes are native to Southeast Asia. The main difference between regular limes and key limes is their size and color. Real limes are usually smaller (about the size of a ping-pong ball) and yellower than Persian limes, which are the common kind you’ll find in stores.
If you cut a key lime in half, you’ll also notice that it has a thinner skin, more seeds, and the juice is more tart and flavorful than regular limes. The key lime gets its name from where it is grown in the Florida Keys in the United States.
What can I use Key Limes for?
Key Lime is a great ingredient for marinades, beverages like lemonade and iced tea, as a garnish, and in countless recipes for its fresh citrus scent and unique tart flavor. You can grate the skin and/or squeeze the juice over fish and seafood, or use it to spice up stir-fries and curries. Of course, it’s also a key ingredient (pun intended?) in desserts like key lime pie.

Where can I find Key Limes?
Depending on where you live, it can be difficult to find fresh Key Limes in grocery stores. Key limes are harvested in Florida and California from June to September and have a short shelf life. If you live in a Key Limes area, grab these babies as soon as they reach the aisle! Otherwise, ask at local farmers markets or try online sellers. Yes, we live in an era where fresh Key Limes can be ordered from sites like Amazon. What a time to be alive!
How can you tell when a Key Lime is ripe?
Key limes are usually picked when they are still green and turn yellow as they ripen. To pick out the best key limes, look for the ripe ones. Ripe key limes are yellowish-green in color and feel a bit heavy and firm (but not hard). Avoid limes, which are rough and dry to the touch.
Can I use regular limes instead?
Yes. If you’re having trouble finding key limes in your area, you can use regular Persian limes in place of key limes in most recipes. The flavor will be slightly different, but they will absolutely work in a pinch.
The best way to store Key Limes
As previously mentioned, Key Limes don’t stay fresh for long. Because of this, it is best to use them immediately. Otherwise, store limes in a plastic bag in the fresh food drawer of your refrigerator for up to 2 weeks.
