- 1 cup fresh blackberries plus extra for garnish
- 4 oz spiced rum or dark rum for deeper flavor
- 2 oz simple syrup
- 1 oz fresh lime juice
- 1 cup ice plus extra for serving
- Lime wheels for garnish
- Sprigs of mint for garnish optional
- Soda water for topping optional, for a lighter cocktail
Muddle the blackberries in the bottom of a cocktail shaker until they’re thoroughly crushed and juicy. Press firmly but not so hard that you break the seeds, which can add bitterness.
Add the rum, simple syrup, and lime juice to the shaker with the muddled blackberries and stir briefly to combine the flavors.
Fill the shaker with ice and secure the lid tightly. Shake vigorously for about 15-20 seconds until the outside of the shaker becomes frosty.
Double-strain the cocktail through a fine-mesh strainer into two chilled cocktail glasses filled with fresh ice. This removes the blackberry seeds and pulp while preserving the rich color and flavor.
Top with a splash of soda water if desired for a slightly fizzy version, though this will lighten the color somewhat.
Garnish each glass with a lime wheel, a few fresh blackberries, and a sprig of mint if using. The bright green against the dark drink creates a striking Halloween contrast.
Serve immediately while the drink is cold and the ice is fresh. For an extra Halloween touch, serve with black straws or add dry ice for a smoking effect (just ensure it’s handled safely).
- For an even darker color, you can let the blackberries macerate in the rum for 1-2 hours before making the cocktail.
- If blackberries aren’t in season, frozen ones work just as well—just thaw them slightly before muddling.
- The cocktail can be made in a larger batch for parties; just multiply the ingredients and strain into a pitcher, but add ice only when serving.
- For a non-alcoholic version, substitute the rum with black tea that’s been brewed strong and cooled.
- The blackberry syrup component (muddled berries + simple syrup) can be made ahead of time and stored in the refrigerator for up to 3 days.
