Classic Daiquiri Recipe: A Crisp, Balanced Cuban Cocktail

A classic daiquiri is a Cuban cocktail made with white rum, fresh lime juice, and sugar syrup, shaken with ice and served straight up. Its appeal is in the balance: rum gives it body, lime keeps it bright, and just enough syrup softens the tartness without hiding either flavor.

Ingredients

2 oz white rum (¼ cup; 60 ml). Choose a clean, unflavored white or lightly aged rum. A Cuban-style light rum is a natural fit, but another straightforward white rum works well.
1 oz fresh lime juice (2 tbsp; 30 ml). Juice a fresh lime just before mixing and strain out seeds. The amount is intentionally generous enough to give the drink its characteristic citrus snap.
¾ oz simple syrup (1 tbsp plus 1½ tsp; about 22 ml). Use plain 1:1 simple syrup, made from equal parts sugar and water by volume, and make sure it is cool. Bottled syrup is convenient; avoid flavored syrups for the classic version.
1 cup ice (about 140 g), preferably firm, cold cubes for shaking. The ice is used to chill and dilute the cocktail, then is left behind when you strain.
1 thin lime wheel, optional, for garnish.

Instructions

Chill the serving glass if you like. Put a coupe or small cocktail glass in the freezer while you gather the ingredients. Even a few minutes helps it stay cold, but this step is optional and does not change the recipe.
Measure the ingredients. Pour the rum, fresh lime juice, and simple syrup into a cocktail shaker. Measuring accurately matters in a drink with only three main ingredients: a little extra lime can make it sharply sour, while too much syrup can flatten the citrus.
Add ice and shake. Fill the shaker with the cup of ice, close it securely, and shake briskly for about 12–15 seconds. The outside should feel very cold. Shaking chills the mixture and adds a small amount of water as the ice melts, which rounds out the strong rum and lime.
Strain into the glass. Remove the chilled glass from the freezer, if using. Strain the cocktail through the shaker’s built-in strainer or a small fine-mesh strainer into the glass. Serve without ice in the glass; the drink should be cold and lightly diluted, not watery.
Garnish and serve promptly. Add a lime wheel to the rim or float it on the surface. Take a small sip before serving a larger batch so you can check the balance; for this single drink, adjust the next one rather than adding syrup or juice blindly to the finished glass. This cocktail is for adults of legal drinking age; drink responsibly.

Tips

Use fresh juice, not bottled lime juice. Freshly squeezed lime gives the drink a clean, lively citrus aroma. Bottled juice can taste muted or more harshly acidic, so it may make the balance less predictable. Roll the lime firmly on the counter before cutting it to help release more juice.
Adjust sweetness a little at a time. Limes vary in size and tartness, and different rums can taste drier or rounder. If your first sip is too sharp, try adding ¼ oz (1½ tsp; about 7 ml) more syrup to the next drink. If it is too sweet, reduce the syrup by the same amount or add a small splash of lime.
Keep the ice cold and the shake short. Fresh, hard ice cools the drink efficiently. Ice that has softened or started melting on the counter can over-dilute the mixture, while an unusually short shake may leave it warm and unbalanced. A brisk 12–15 seconds is a useful target; shaking much longer is rarely necessary.
Simple syrup is easy to replace. If you do not have it, dissolve superfine sugar directly in the lime juice before adding the rum, then taste to make sure no grains remain. It can take longer to dissolve and may leave a slightly less smooth texture. Regular granulated sugar works best when dissolved fully rather than simply stirred into the finished drink.

Serving Suggestions

Serve a daiquiri in a chilled coupe or small stemmed cocktail glass, without ice. The stem helps keep warm hands away from the drink, and the smaller serving lets the aroma of lime and rum stay noticeable until the last sip. A thin lime wheel is an optional, restrained garnish; a wedge can be squeezed in by someone who prefers extra tartness, though it is not needed when the recipe is balanced.

This cocktail pairs naturally with salty, crisp snacks such as fried plantain chips, salted nuts, or crackers. It also works alongside a small plate of grilled seafood, citrus-marinated vegetables, or other light savory bites. Keep portions modest and flavors uncomplicated so the drink’s lime and rum remain clear. For a gathering, serve it as a pre-dinner cocktail and mix each round just before pouring rather than leaving finished drinks sitting in a pitcher.

Variations

Make it drier or sweeter. The classic three-part formula can be tuned to taste without changing its character. For a drier, more lime-forward drink, use ½ oz (1 tbsp; 15 ml) syrup. For a softer, sweeter one, increase the syrup to 1 oz (2 tbsp; 30 ml). Change only the syrup at first, since increasing lime as well can make it difficult to judge the balance.

Try lightly aged rum. A lightly aged rum can bring gentle vanilla, oak, or caramel notes and a rounder finish. It will taste less neutral than white rum, so keep the lime and syrup measurements the same for the first try. Dark, heavily spiced, or strongly flavored rum will move the drink further from the clean profile of a classic daiquiri.

Make a frozen daiquiri. For a blended version, combine the rum, lime juice, syrup, and about 1½ cups (210 g) ice in a blender. Blend just until smooth, adding a small amount of ice if you want a thicker texture. This changes the drink’s texture and dilution, so it will not taste exactly like the shaken, straight-up version. Do not add sweetened fruit unless you also adjust the syrup and lime to account for it.

Scale for a small group. For four drinks, combine 8 oz (1 cup; 240 ml) rum, 4 oz (½ cup; 120 ml) lime juice, and 3 oz (⅜ cup; about 90 ml) syrup in a covered container and refrigerate. Shake each portion with fresh ice when ready to serve, or shake the whole batch in two rounds so there is room for the liquid and ice to move. Do not add ice to the storage container, where it will melt and dilute the batch.

Storage and Reheating

A daiquiri is best shaken and served immediately. Ice melts quickly, so a finished drink becomes progressively weaker and less crisp as it sits; there is no useful way to reheat or restore it. If you cannot serve it right away, strain it into a covered container and refrigerate it promptly, within 2 hours. For best flavor, drink it within 24 hours, then shake briefly with fresh ice before serving. It may still be safe beyond that short quality window if kept cold, but its brightness and balance will decline.

For advance preparation, mix only the rum, lime juice, and syrup, cover, and refrigerate for up to 24 hours. Shake each serving with ice just before pouring. Fresh lime juice can lose some of its aroma during storage, so making the base on the day you plan to serve it gives the liveliest flavor. Keep simple syrup refrigerated according to its label; homemade syrup should also be kept covered and refrigerated. Never store a finished cocktail at room temperature for an extended period.

Frequently Asked Questions

Is a classic daiquiri supposed to be sweet?
A classic daiquiri should be balanced rather than sugary. Lime is clearly present, but the syrup softens its sharp edge, while rum remains easy to taste. Start with the listed ¾ oz syrup, then make small adjustments based on the lime and rum you have. A thick, sweet, blended fruit drink is a different style, not the standard shaken daiquiri.

Can I make a daiquiri without a cocktail shaker?
Yes. Use a clean jar with a tight-fitting lid, add the ingredients and ice, close it securely, and shake for 12–15 seconds. Open it carefully, then pour through a small strainer into the glass. A shaker is convenient, but the important parts are secure closure, enough ice, a vigorous shake, and straining away the ice afterward.

What kind of rum is best?
A neutral white rum keeps the drink crisp and lets the lime stand out. A lightly aged rum is also a good choice if you want a little more depth. Avoid assuming that darker or spiced rum is automatically better: those stronger flavors can take over the simple citrus-and-rum balance that defines this recipe. Use a rum you enjoy sipping.

Can I use bottled lime juice or lemon instead?
Fresh lime juice is the best choice for the expected flavor. Bottled lime juice can work in a pinch, but taste it first because its acidity and aroma vary by product; adjust the syrup in small amounts. Lemon juice makes a pleasant citrus cocktail but gives a different flavor, so it is not a direct substitute if you want the familiar lime-led daiquiri.

How do I make simple syrup if I do not have any?
Stir equal parts sugar and water by volume until the sugar dissolves, then let the syrup cool before measuring it into the drink. For a small amount, mix 2 tbsp sugar with 2 tbsp water; this makes more than one daiquiri needs. Do not pour warm syrup into the shaker, because it can warm the drink and melt the ice faster.

Why did my daiquiri turn out watery?
The likely causes are ice that was already melting, a very long shake, or a cocktail left standing after straining. Use cold, firm cubes, shake briskly for about 12–15 seconds, and serve as soon as you strain. A drink can also taste thin if it has too little rum or lime relative to the amount of syrup, so measure rather than pouring by eye.
