How to Make a great Key Lime Mojito! This is a great classic cocktail recipe!

This is what happens when Karlynn and I go to the grocery store. There could be worse things, for sure, but on a recent trip I found this teensy bag of key limes and decided I absolutely HAD to make something with them.  I landed on a Key Lime Mojito because they also had fresh mint so it seemed like a natural choice.


The process of getting ready to make a cocktail is a fun one. The only part where I sometimes struggle is trying to decide which glasses to use but I saw these ones sitting in our liquor cabinet and immediately figured they’d make a perfect Mojito glass. These epic looking pilsners totally fit the drink perfectly and they are damn sexy looking glasses. I don’t know if that’s an onion or a pineapple on the side of them but either way, beautiful.

One of the challenges of this recipe was to actually squeeze juice out of these tiny key limes. I used something like this:

Simply cut the key limes in half and put both halves in, then squeeze the juice into a bowl first. You can then pour it into a shot glass for measurement purposes.

I also used an ice crusher which you can pick up from here:

These are handy to keep around, especially for spring / summer cocktails so if you do have one (or order one), I’ll make sure to provide plenty of recipes to make use of it.

Ok, for this recipe you will need:

  • White Rum (or Coconut Rum, which one reader suggested and I think would probably taste fantastic)
  • Approximately 8 key limes (for 2 drinks because it takes about 4 key limes to produce around 1 oz of juice if you squeeze really hard with the juicer)
  • Club soda
  • Simple syrup
  • Fresh mint
