GSM Mojito Recipe with Gin, Strawberry, and Mint

A mojito is a Cuban-style highball built around mint, lime, sweetener, spirits, and sparkling water. GSM is not a universally standardized cocktail name, so this recipe uses it for a gin, strawberry, and mint variation: juicy berries and crisp gin make a bright, easy-to-mix drink served cold over ice.

Ingredients

1 cup hulled, sliced strawberries (150 g), plus 2 small pieces for garnish if desired
12 fresh mint leaves (about 2 g), plus 2 small sprigs for garnish
2 tablespoons fresh lime juice (30 ml), from about 1 lime; cut the squeezed lime into wedges for garnish
1 ounce simple syrup (30 ml)
3 fluid ounces gin (90 ml)
1 cup chilled club soda or sparkling water (240 ml), plus a little more if needed
2 cups ice (about 280 g), preferably crushed or small cubes

Instructions

Prepare the glasses. Choose two sturdy highball glasses, each holding about 10 to 12 fluid ounces (300 to 350 ml). Rinse and dry the mint sprigs, slice the strawberries, and juice the lime. Keep the club soda cold so the finished drinks stay lively.
Muddle the fruit and mint. Divide the sliced strawberries and mint leaves between the glasses. Add 1 tablespoon (15 ml) lime juice and 1/2 ounce (15 ml) simple syrup to each glass. Press and gently twist with a muddler or the back of a wooden spoon for about 10 to 15 seconds, just until the berries release juice and the mint smells fragrant. Avoid grinding the leaves into a paste.
Add the gin. Pour 1 1/2 fluid ounces (45 ml) gin into each glass. Stir each mixture several times, scraping the bottom lightly so the syrup and berry juice are evenly distributed. If you prefer a less spirit-forward drink, begin with 1 fluid ounce (30 ml) gin per glass and adjust after tasting.
Fill with ice. Add about 1 cup (140 g) ice to each glass, leaving a little room at the top. Crushed ice chills the drink quickly and gives a classic, frosty highball feel; small cubes melt more slowly and are convenient when crushed ice is unavailable.
Top with soda. Pour about 1/2 cup (120 ml) chilled club soda into each glass, then stir gently once or twice from the bottom upward. Taste a small sip. Add a splash more soda for a lighter drink, or a little extra syrup if your strawberries are tart.
Garnish and serve. Add a lime wedge, a strawberry piece, and a mint sprig to each glass. Lightly clap the mint sprig between your palms before adding it; this releases its aroma without bruising it heavily. Serve immediately with a straw or cocktail spoon.

Tips

Muddle gently. Mint gives a clean, cooling aroma when it is pressed lightly. Shredding or pulverizing the leaves can make the drink taste grassy and leave small fragments throughout the glass. If you do not have a muddler, use the rounded end of a wooden spoon and work slowly.
Choose ripe berries. Fragrant, fully red strawberries usually provide enough sweetness and juice. If yours are very sweet, start with a little less syrup; if they are pale or tart, add syrup gradually after mixing. Frozen strawberries can work after thawing and draining, but they will make the mixture softer and less fresh-tasting.
Use fresh lime and cold soda. Bottled lime juice can taste flat or sharp beside the mint, so fresh juice is preferable. Add the soda at the end and stir gently: vigorous mixing knocks out carbonation and can flatten the drink before it reaches the table.
Adjust the sweetness without over-muddling. Simple syrup dissolves more evenly than granulated sugar in a cold drink. If you only have sugar, dissolve it in the lime juice and berry juice before adding ice and soda; adding dry sugar after the glass is filled can leave crystals at the bottom.

Serving Suggestions

Serve the drinks as soon as they are assembled, while the soda is fizzy and the ice is still firm. Highball glasses show off the strawberry color and leave enough room for ice and a garnish. A short straw or cocktail spoon helps bring the fruit and mint up from the bottom, where the muddled mixture settles. If you are serving a group, set out lime wedges and extra soda so guests can adjust the tartness and strength in their own glasses.

This cocktail pairs naturally with salty, crisp snacks such as roasted nuts, plantain chips, tortilla chips, or lightly seasoned popcorn. It also works alongside grilled vegetables, seafood, or citrusy appetizers; keep the food flavors fairly simple so they do not drown out the mint and berry. This alcoholic drink is for adults of legal drinking age; drink responsibly.

Variations

Classic rum mojito: Replace the gin with 3 fluid ounces (90 ml) white rum for two drinks. This brings the recipe closer to the familiar Cuban-style mojito profile, while strawberry still makes it a fruit variation rather than a plain classic. Use the same method and taste before adding extra syrup.

Ginger version: Replace up to half of the club soda with chilled ginger beer. It adds a spicy, sweeter finish, so start with less simple syrup and adjust only after tasting. For a drier result, use ginger ale only if you prefer a noticeably sweeter cocktail.

Nonalcoholic strawberry-mint cooler: Leave out the gin and add another 1/2 cup (120 ml) chilled club soda to each pair of drinks, or top each glass to taste. For a little more body, use a nonalcoholic gin-style spirit according to its label, since products vary in strength and flavor. Keep the lime and syrup amounts flexible: without the gin, the fruit may taste sweeter and less balanced.

Other fruit: Swap the strawberries for 1 cup (150 g) chopped ripe peaches, raspberries, or blackberries. Raspberries break down quickly, so press them only briefly; blackberries can leave seeds in the drink, which you can strain out before adding ice if you prefer a smoother texture. Peach is softer and less tart, so a little extra lime may help balance it.

Storage and Reheating

A finished mojito is best immediately. Ice melts, soda loses its fizz, and the muddled mint can turn dull, so storing a fully assembled drink is not a good make-ahead strategy. If there is a leftover portion, cover it and refrigerate it within 2 hours; for best quality, drink it within 24 hours. Do not leave a glass with fresh fruit and herbs sitting at room temperature for an extended period.

For advance preparation, muddle the strawberries, mint, lime juice, and syrup up to 4 hours ahead, cover the mixture, and refrigerate it. Add the gin, ice, and soda only when serving. The mint may darken slightly as it rests, so a freshly muddled batch will have the brightest aroma. Once opened, keep any leftover club soda tightly capped and refrigerated, and use it while it is still well carbonated.

Simple syrup can be made ahead and kept in a clean, covered container in the refrigerator for about 1 week; discard it if its appearance or smell changes. There is no reheating step for this cold cocktail.

Frequently Asked Questions

What does GSM mean in a mojito recipe?
GSM does not have one widely established meaning for mojitos. In this version it refers to the main flavor combination of gin, strawberry, and mint. Since the abbreviation can mean different things in different recipe contexts, check the ingredients when you see it elsewhere.

Can I make this with white rum instead of gin?
Yes. Use the same amount of white rum as gin for a more familiar mojito character. Rum has a different flavor from gin, so the finished drink will not taste identical, but lime, mint, berries, and soda work well with either spirit.

Can I make a pitcher for a party?
Yes, but do not add ice or soda to the pitcher in advance. Multiply the fruit, mint, lime, syrup, and gin by the number of servings, muddle gently in a large container, and refrigerate for up to 4 hours. Pour over ice and top each glass with soda just before serving for better fizz and control over dilution.

What can I use instead of simple syrup?
Agave syrup or honey syrup can replace simple syrup in the same starting amount, though each changes the taste slightly. Agave has a mild flavor and can make the drink feel a little rounder; honey adds a distinct floral note. Stir either into the lime and fruit mixture before adding ice so it disperses evenly.

Can I use frozen strawberries?
Yes. Thaw them first and drain excess liquid so the drink does not become watery. Frozen berries tend to be softer than fresh ones and may produce a cloudier, more pulpy drink, but their flavor is useful when ripe fresh strawberries are unavailable.

How do I make the drink less sweet or less strong?
For less sweetness, reduce the syrup to 1/2 ounce (15 ml) for the two-drink batch and add more only if needed. For a lighter drink, use less gin and top with extra soda. Make one adjustment at a time and taste before adding more lime, since extra lime will make the drink sharper rather than simply less sweet.
