This cucumber-lime gin cooler is bright, lightly sweet, and topped with sparkling water for an easy, refreshing drink. It comes together in minutes, and muddled cucumber and fresh lime keep the gin tasting crisp rather than heavy.
Ingredients
- 2 ounces gin
- 4 thin cucumber slices, plus 1 slice to garnish
- ¾ ounce freshly squeezed lime juice
- ½ ounce simple syrup
- 3 ounces chilled sparkling water, or enough to top the glass
- 1 cup ice, plus extra for serving
- 1 small sprig fresh mint, for garnish (optional)
Instructions
- Chill a highball glass in the freezer for about 5 minutes, or fill it with ice water while you prepare the drink. If using the ice water, pour it out before serving.
- Put the cucumber slices in a cocktail shaker. Press them gently with a muddler or the back of a wooden spoon just until they release their juice. Avoid crushing them into a paste, which can make the drink bitter or pulpy.
- Add the gin, lime juice, simple syrup, and 1 cup of ice to the shaker. Seal it and shake firmly for 10 to 15 seconds, until the outside feels cold.
- Fill the chilled glass with fresh ice. Strain the drink into it, using a fine-mesh strainer if you want to catch small cucumber pieces. Top with chilled sparkling water and stir once, gently.
- Garnish with a cucumber slice and, if desired, a lightly slapped mint sprig. Serve right away while the bubbles are lively and the ice is firm.
Tips
- Measure the citrus and syrup. Lime juice varies in sharpness, so taste the drink before adding the sparkling water. If it is too tart, stir in a teaspoon of syrup; if it is too sweet, add a small squeeze of lime.
- Choose a fresh cucumber. English cucumber is convenient because its skin is usually mild and its seeds are small. If your cucumber has a tough or bitter peel, peel it before muddling.
- Keep the fizz cold. Refrigerate the sparkling water until you are ready to pour it. Warm soda loses carbonation faster and dilutes the drink as the ice melts.
- Make simple syrup ahead. Stir equal parts sugar and hot water until the sugar dissolves, then cool completely. Store it covered in the refrigerator and use within about 2 weeks; discard it sooner if it becomes cloudy, develops an off smell, or shows signs of mold.
Serving Suggestions
Serve this cooler in a tall glass with plenty of fresh ice, alongside grilled vegetables, fish tacos, shrimp, or a salty snack such as olives or roasted nuts. Its citrus and cucumber notes also work well with mild cheeses and herb-forward salads. For a small gathering, make each drink individually so the soda stays fizzy; set out lime wedges, cucumber ribbons, and mint for easy garnishes.
For a more polished look, run a cucumber ribbon along the inside of the glass before filling it. Use a vegetable peeler to make the ribbon, and keep the garnish refrigerated until serving. A thin lime wheel is another simple option, but avoid adding too much peel or juice to the finished glass, as it can overwhelm the balanced, clean flavor.
Variations
Make it a cucumber gin fizz: Add ½ ounce more lime juice and ½ ounce more syrup, shake as directed, then top with about 2 ounces of sparkling water in a larger glass. This version is a little sharper and more citrus-forward.
Use tonic: Replace the sparkling water with 3 ounces of chilled tonic water. Tonic adds sweetness and bitterness, so start with just ¼ ounce of syrup and adjust to taste.
Add berries: Muddle 3 or 4 raspberries with the cucumber for a rosy, fruity drink. Strain carefully to remove seeds. A few sliced strawberries work too, though they make the drink softer and sweeter.
Make a no-alcohol cooler: Leave out the gin and use 2 ounces of chilled nonalcoholic gin alternative, or simply add an extra 2 ounces of sparkling water. Taste and adjust the lime and syrup, since alcohol-free alternatives differ in flavor and sweetness.
Storage and Reheating
This cocktail is best made and served immediately. Once shaken and topped with sparkling water, it will lose its fizz and become diluted as the ice melts; do not store leftovers for later or try to re-carbonate them. Do not leave a prepared drink at room temperature for more than 2 hours, or more than 1 hour if the temperature is above 90°F (32°C). Alcohol does not make a mixed drink exempt from sensible food-safety handling.
You can prepare the cucumber, gin, lime juice, and syrup mixture without ice up to 4 hours ahead. Keep it covered in the refrigerator, then shake it with ice and add freshly opened sparkling water just before serving. For best flavor and texture, do not muddle the cucumber more than a few hours in advance. There is no reheating step; serve this drink cold.
Frequently Asked Questions
What kind of gin works best?
Use a gin you enjoy drinking, since its botanical flavor is noticeable in a simple cocktail. A classic London dry gin gives a crisp, juniper-forward result; a softer contemporary gin can let the cucumber and lime stand out more.
Can I make this without a cocktail shaker?
Yes. Muddle the cucumber in a sturdy glass or jar, add the gin, lime, syrup, and ice, then cover securely and shake. If you cannot shake it safely, stir the ingredients briskly with ice for about 20 seconds and strain into a glass with fresh ice.
Can I use bottled lime juice?
Fresh lime juice is best because it tastes brighter and less processed. Bottled juice can work in a pinch; start with the same amount, then taste and adjust before adding the sparkling water.
How do I make simple syrup?
Combine ½ cup granulated sugar with ½ cup hot water and stir until completely dissolved. Cool before using. This makes more than one cocktail’s worth; refrigerate the extra in a clean, covered container and use it within about 2 weeks.
Can I make a pitcher for a party?
Multiply the gin, cucumber, lime, and syrup by the number of servings, then combine and chill the mixture without ice or sparkling water for up to 4 hours. Add the soda and ice to individual glasses when serving rather than to the pitcher, so the drinks stay fizzy and do not become watered down.
Why does my drink taste bitter?
Over-muddled cucumber, a bitter peel, or too much lime zest can contribute. Press cucumber gently rather than grinding it, peel it if necessary, and use juice rather than squeezing lime peel into the shaker. A little extra syrup can soften mild bitterness.
