What are Key Limes?
Key limes are the smaller, sweeter cousin to regular limes. They're also known as the Mexican Lime or the West Indies Lime. They have a unique floral flavor that's tart without being too acidic.
In the US, key limes are in season from June to August so you can usually only find them at the grocery store during those months, which is why key lime pie is such a popular summer treat! I always have extra key limes in the summer which is why I decided these key lime margaritas were a necessity!
However, if you aren't lucky enough to find fresh key limes at the store, bottled key lime juice works great!Nellie & Joe's key lime juiceis delicious and is sold at most grocery stores as well as amazon.
Ingredient Notes
- Tequila- My favorite tequila for margaritas is1800 Silver Tequilabut you can use whatever you prefer!
- Key Lime Juice- The star of the show! I always prefer using fresh key limes, but if you can't find them you can use bottled key lime juice!
- Orange Liqueur- I love adding orange liqueur to margaritas always, but it's completely optional! My favorite isGrand Marnier!
- Simple Syrup- You can add as little or as much simple syrup as you like! I like my margaritas to be pretty tangy but if you like it sweeter, definitely add more syrup! See my notes below for making your own key lime simple syrup!
How to Make Key Lime Simple Syrup
I always make my own simple syrup for co*cktails because it's so easy and paying for it seems silly to me! You can also add in different herbs or fruit for a delightfully flavored simple syrup. Since we have leftover key limes from squeezing out the key lime juice, you can just add those in!
- ½ cupgranulated sugar
- ½ cupwater
- key lime peels(optional)
- Add the sugar, water, and leftover key lime peels to a small saucepan over medium heat.
- Stir until sugar is completely dissolved.
- Let cool completely to room temperature, then strain into a glass jar and seal tightly with a lid.
- Store in the fridge for up to a month!
co*cktail Serving Tips
I love my key lime margaritas on the rocks with a salt rim, but you can easily make these frozen instead! Just throw the ingredients in a blender with ice!
To make a salt rim, rub a small amount of key lime juice or simple syrup along the edge of your glass. Pour a small amount of margarita salt (or kosher salt) on a plate and gently press the edges of the glass into the salt.

This margarita was delicious! I used the key lime juice instead of key limes and I thought it was great. Definitely one I will serve to guests!

It's good, but better with more simple syrup, IMO. I also only used regular simple syrup, not key lime simple. A nice change from a regular margarita and a great use of leftover key lime juice after making key lime pie.Loading...

This was a super fun recipe to make for a taco bike ride I just attended. The general consensus was that it was too tart but I think knowing that it is key lime, that goes with the territory. I did double the key lime simple syrup and still had comments it was too tart. My husband and I loved it so the 4 stars is a combination of about 10 people taste testing it. If you like key lime, you are more inclined to love this recipe. 🙂Loading...

Yeah, while appreciate the effort here, I think the "key lime" simple syrup is an unnecessary bit of fluff. You're adding boatloads of pure lime juice to the drink already, so a miniscule amount of added lime via the lime peels in the syrup is overkill in my view. And yes, with or without it, this recipe is a bit too tart for my tastes.
