A boozy treat from Havana Central, this frozen sorbet is sure to be a crowd-pleaser at your next party.
In a glass pitcher, add limes and mint. Muddle until mint breaks up. Add rum and simple syrup. (Optional) Add fruit purée. Stir until all ingredients are mixed. Add Sprite and soda, then gently stir. Pour the mojito mixture into a 9-inch-by-13-inch-by-2-inch cake pan. Cover with plastic wrap and freeze overnight. Spoon the frozen mojito into a chilled martini glass and serve.
