A classic daiquiri is three ingredients and maybe four ounces of liquid. It doesn't look like much. But when the ratio is right, rum, lime, and sweetener come together in a way that makes every frozen version you've ever had feel like a compromise.
This daiquiri recipe uses rich simple syrup instead of regular, and that one change is what keeps the drink from tipping too sour or too sweet.
What Makes This Different
The flavor is sharp and bright: tart lime, smooth rum, and just enough sweetness to hold everything in balance. Rich simple syrup is twice as concentrated as regular, which means less volume, a tighter drink, and a slight viscosity that regular syrup can't match.
All you need is 5 minutes and a cocktail shaker. The one thing to know before you start: rich simple syrup and regular simple syrup are not interchangeable here, and if you don't have rich on hand, I've linked our recipe below.

What I Learned Making This Recipe
When I first set out to make a good daiquiri at home, I tested a handful of different ratios. Most recipes I found called for a significant amount of lime juice and a minimal amount of sweetener, and they all landed in the same place: sharp to the point of puckering, with the rum either fighting for attention or hiding behind the citrus entirely.
The shift to rich simple syrup came from reading about how some bar programs use it specifically because it makes cocktails taste more balanced without adding more liquid. Even though rich syrup is sweeter per ounce, a smaller amount goes further. The result was a drink where all three ingredients were pulling together instead of competing. The texture changed, too: a very slight body that regular simple syrup doesn't have, and that weight makes the drink feel more finished in the glass.

Ingredients and Substitutions
- Rum: White rum is traditional and what I recommend for this recipe. The flavor is clean and neutral enough to let the lime do its work without competing. Gold rum is a fine substitute if that's what you have. It adds a slightly warmer, more caramel note. Either way, spend a few extra dollars on something smooth. With only three ingredients, the rum is not a background player.
- Lime juice: Fresh squeezed only. Bottled lime juice has a cooked, slightly flat quality that's noticeable in a drink this simple. You'll need about half of a good sized lime for 1 ounce.
- Rich simple syrup: Made with a 2:1 ratio of sugar to water, which makes it more concentrated and slightly thicker than regular simple syrup. That concentration is what allows you to sweeten the drink without adding excess volume, and the slight viscosity is part of what makes this recipe feel polished. You can buy it, but it takes about 5 minutes to make at home. My rich simple syrup recipe walks you through the process.
How to Make
- Fill a cocktail shaker with ice. Add the rum, lime juice, and rich simple syrup.
- Shake hard for at least 20 seconds, until the outside of the shaker is very cold.
- Strain through a fine-mesh strainer into a chilled coupe glass.
- Garnish with a lime wheel if you'd like, and serve immediately.
Before You Make This
- Chill the glass first. Fill it with ice water while you're getting everything ready, then dump it right before you strain. A warm glass warms the drink immediately. This takes 30 seconds and it matters.
- Shake harder and longer than you think. Twenty seconds minimum, and shake hard the whole time. You're not just mixing the ingredients. You're chilling and diluting the drink, and that dilution is part of what gets the balance right. A 10-second shake produces a noticeably different cocktail.
- Taste before you strain. Open the shaker and taste with a clean bar spoon. If it's pulling too sour, add a splash more simple syrup and shake for 5 more seconds. The ratio is a starting point, not a rule.
- Use a fine-mesh strainer over the shaker's built-in strainer. Double-straining keeps ice chips out and gives you a cleaner, clearer drink.
Serving Suggestions
A classic daiquiri is traditionally served in a coupe glass. A martini glass works too; the wider rim brings the aroma forward a little more. Either way, keep it small. This is a concentrated drink under 4 ounces, and it's meant to be sipped cold.
The lime wheel garnish is straightforward: a thin slice from the lime you already squeezed. You can skip it, but it's a nice touch if you're making these for people.
If you're in the mood for another shaker cocktail with a different spirit, Lisa's Lemon Drop Martini uses the same method and is just as quick to put together.
FAQs
A gimlet follows the same structure: a spirit, citrus, and a sweetener. The difference is the spirit. A daiquiri uses rum; a gimlet traditionally uses gin, though vodka gimlets are common, too. The flavor lands in a different place entirely: gin brings an herbal, botanical quality that rum doesn't have, and the drink reads as drier and more complex. If you want to try the same technique with gin, our Gin Gimlet made with elderflower liqueur is a good place to start.
Yes, with one condition. Combine the rum, lime juice, and rich simple syrup in a pitcher and refrigerate for up to a day ahead. Just don't add ice yet. When guests arrive, pour from the pitcher into a cocktail shaker and shake in rounds of two or three drinks at a time. Shaking is what chills and dilutes the drink correctly, and you obviously can't do that with a pitcher. A daiquiri that's been sitting on ice is a watered-down daiquiri.

I made this with fresh lime juice I squeezed and it was great. Then I snuck in what you call "fake" stuff, I.E. a bottled lime juice - which I don't consider "fake" - and while I wouldn't say it was as great as the fresh, it was still very good. It didn't taste "off" to me at all. And when I'm the one drinking it, my opinion is the only one that matters.
