Full Ingredients
For the Cocktail
- 10 medium fresh sweet basil leaves, rinsed and thoroughly dried
- 3/4 ounce simple syrup, prepared with equal parts granulated sugar and water by volume
- 2 ounces London dry gin
- 3/4 ounce freshly squeezed lemon juice, strained to remove seeds and excess pulp
- 1 cup ice cubes, for shaking
For Serving
- 1 large 2-inch ice cube
- 1 small fresh basil sprig
- 1 thin lemon wheel

Step-by-Step Instructions
Step 1: Chill the serving glass
Place an old-fashioned glass in a 0°F freezer for 5 minutes while you prepare the cocktail. Alternatively, fill the glass with ice and cold water for 3 minutes, then empty and dry it before serving. A properly chilled glass keeps the drink crisp without requiring excessive dilution.
Step 2: Muddle the basil
Place the 10 basil leaves and 3/4 ounce simple syrup in the bottom of a cocktail shaker. Use a muddler to press and gently twist the leaves 8 to 10 times. The syrup should become fragrant and lightly green. Apply enough pressure to release the basil oils, but avoid grinding the leaves into a paste, which can introduce bitter flavors and tiny pieces into the drink.
Step 3: Add the gin and lemon
Pour 2 ounces of London dry gin and 3/4 ounce of freshly squeezed lemon juice into the shaker. Give the mixture a brief stir with a bar spoon so the syrup does not remain concentrated at the bottom.
Step 4: Shake until thoroughly chilled
Add 1 cup of ice cubes to the shaker. Seal it tightly and shake as vigorously as possible for 12 to 15 seconds. The outside of a metal shaker should feel very cold and develop a light layer of frost or condensation. Vigorous shaking chills the drink, provides the proper amount of dilution, and helps distribute the basil oils throughout the cocktail.
Step 5: Double-strain the cocktail
Place the large 2-inch ice cube in the chilled glass. Pour the cocktail through both a cocktail strainer and a fine-mesh strainer into the glass. Double-straining catches torn basil and lemon pulp, leaving the drink smooth while retaining its vibrant green color and herbal aroma.
Step 6: Garnish and serve
Gently tap the basil sprig against the palm of your hand once to release its aroma, then place it beside the ice cube. Add the thin lemon wheel at the rim of the glass. Serve immediately while the cocktail is approximately 35°F to 40°F and the basil aroma is at its brightest.
Pro Tips
- Choose tender basil: Use bright green leaves without dark spots, tough stems, or wilted edges. Sweet basil gives the most classic flavor.
- Use fresh lemon juice: Bottled juice often tastes muted or harsh. Squeeze and strain the lemon shortly before mixing.
- Measure with a jigger: The equal quantities of lemon juice and simple syrup are important for a balanced sweet-tart finish.
- Shake vigorously: A forceful 12- to 15-second shake extracts more basil character and gives the drink its lively, lightly opaque appearance.
- Adjust carefully: For a sweeter drink, add an extra 1/8 ounce simple syrup. For a sharper drink, add an extra 1/8 ounce lemon juice.
Variations
- Cucumber Basil Smash: Muddle 3 cucumber slices, each 1/4 inch thick, with the basil and syrup before adding the remaining ingredients.
- Elderflower Basil Smash: Use 1/2 ounce simple syrup and add 1/4 ounce elderflower liqueur for a floral finish.
- Alcohol-Free Basil Smash: Replace the 2 ounces of gin with 2 ounces of a nonalcoholic botanical spirit and prepare the rest of the recipe as written.
Storage & Make-Ahead
A Gin Basil Smash is best shaken and served immediately; storing the finished drink causes the basil to darken and the citrus flavor to fade. Lemon juice may be squeezed, strained, and refrigerated in an airtight container at 40°F or below for up to 8 hours. To make simple syrup, combine 1/2 cup granulated sugar and 1/2 cup filtered water in a small saucepan. Warm over medium-low heat for 3 to 4 minutes, stirring until the sugar dissolves and the syrup reaches approximately 190°F; do not boil. Cool for 30 minutes, transfer to a clean airtight container, and refrigerate at 40°F or below for up to 1 month. Keep the basil leaves whole and refrigerated between lightly damp paper towels, then muddle them only when you are ready to make the drink.
