This Easy Frozen Daiquiri is made in about 10 minutes and only requires 4 ingredients. The result is a cold, slushy, boozy drink full of sweet and tart key lime flavor.

I love the occasional cocktail or frozen drink. Whether it’s a raspberry martini, salty dog, or a blackberry mojito, you can count in me for a fruity, tropical drink, especially when they’re easy to prepare.

During the summer months, frozen drinks are even better. All you need is a blender that can handle crushing ice, a few ingredients, and you’re in business.

Some of my most favorite ingredients to use in cocktails are fresh mint and key lime juice. Fresh mint is a common ingredient in our mojitos.

In fact, we use it in all of them from our classic mojito, strawberry mojito, blueberry mojitos, and of course, in our coconut mojitos. Real key lime juice is another favorite ingredient.

We use it in everything from key lime martinis to key lime ice cream. It’s no surprise that both would show up in our frozen daiquiri.

I decided to use key lime juice instead of regular lime juice, because it gives the daiquiri a nice lime flavor that doesn’t get lost in the other ingredients. Since key lime juice is fairly tart, it doesn’t take much and doesn’t melt the ice either.

This is the perfect drink for sharing. It’s great for cookouts, barbecues, or get togethers.

How to make a frozen daiquiri:

  • Process until smooth.
  • Pour into glasses, and garnish with fresh lime wedges and straws. Enjoy immediately!

What’s the difference between lime juice and key lime juice?

Key limes are seasonally grown in Florida and California but can grow in Mexico year-round. They’re smaller in size than Persian or Tahitian limes, and are about the size of a ping pong ball or slightly larger.

Key limes are slightly yellow in color and contain far more seeds than larger limes, and their juice is more tart and very aromatic.

The juice seems to have a smooth, more distinct flavor when used in baking and cooking. We use it for key lime fudge and key lime cheesecake dip instead of using Persian lime juice.

Persian or Tahitian limes are larger in size than key limes. They are oval in shape, and resemble a green lemon.

They are the variety most commonly sold in supermarkets and have a longer shelf life than key limes due to their thick peels. Their juice is also tart but doesn’t seem quite as concentrated as key lime juice and not as distinct in flavor.

Can you use lime juice in place of key lime juice?

Yes, absolutely! We used 1 ounce of key lime juice for the daiquiris and recommend using 1-2 ounces of lime juice in place of the key lime juice. Adjust depending on tastes. A bit more ice may be needed to compensate for the extra liquid.

Can you store frozen daiquiris in the freezer or refrigerator for later?

We do not recommend storing frozen daiquiris. They are best enjoyed immediately.

Can you use coconut rum in place of white rum in a frozen daiquiri?

Yes, coconut rum would taste great in place of the white rum in a daiquiri. It would turn this drink into a tropical cocktail.

Can you use a flavored simple syrup?

Yes! Try adding cherry simple syrup, blackberry simple syrup, or even blueberry simple syrup to add a different flavor to the frozen daiquiri. Just make sure whatever flavor you choose tastes good with lime.
