The Daiquiri has three ingredients: rum, lime juice and sugar. That makes it the best drink for learning how a cocktail is balanced, because there is nowhere to hide. Change the lime by a few millilitres and it goes from flat to sharp. Once you can taste why, you can fix almost any sour you make.
| Ingredient | Measure |
|---|---|
| White rum | 60 ml (2 oz) |
| Fresh lime juice | 20–25 ml (¾ oz) |
| Simple syrup (1:1 sugar to water) | 10–15 ml (⅓–½ oz) |
Method: shaken. Pour everything into a shaker, fill it with ice, and shake hard for about 12 seconds. Strain into a chilled coupe or small cocktail glass. Garnish: a thin lime wheel or nothing at all.
The IBA (the International Bartenders Association) lists a similar spec with 60 ml of rum, 20 ml of lime and a little sugar. Many bartenders prefer slightly more lime and syrup because shaking with ice adds water, which softens both the sourness and the sweetness.
Move the sliders and see what the glass would taste like. The rule of thumb behind it: a sour drink wants roughly 2 parts spirit, 1 part sour, 1 part sweet by strength, and the syrup you use changes how much "sweet" you need.
Lime juice is acidic, and acid tastes sharp. Sugar tastes sweet and also makes acid taste rounder. The two cancel each other out without disappearing, which is why a good sour tastes bright and soft at the same time. Rum sits underneath with a little sweetness of its own and a gentle grassy or caramel note.
Ice matters as much as the ingredients. Shaking chills the drink and melts some ice into it. That water is roughly a quarter to a third of the final volume and it is what makes the drink smooth instead of harsh. Skip the shake and stir it with no ice, and the same ingredients taste sharper and hotter.
Use fresh lime juice, squeezed the same day. Bottled juice tastes flatter and often carries a bitter, cooked edge. If your limes are very tart, add a touch more syrup; if they are sweet and juicy, pull it back.
The usual story is that an American mining engineer, Jennings Cox, mixed rum, lime and sugar for guests around the time of the Spanish–American War in 1898, and named the drink after Daiquirí, a beach and iron mine near Santiago de Cuba. Not everyone agrees on the details, but the origin in Cuba is widely accepted. Naval officer Lucius Johnson is credited with bringing it to the Army and Navy Club in Washington around 1909. In Havana, bartender Constantino Ribalaigua at El Floridita later refined it further.
A Daiquiri is a strong drink for its size. Pour it, sip it, and have water alongside.
Two parts spirit, one part sour, one part sweet, then adjust by taste.
Start at 60 / 22 / 12 and taste it. Too sharp? Add 3 ml of syrup. Too sweet? Add 3 ml of lime. Change one thing at a time and the drink teaches you the rest.
