01 - Combine sugar and water in a small saucepan over medium heat, stirring constantly until the sugar fully dissolves. Remove from heat and let cool completely.
02 - Add the mango cubes, coconut cream, lime zest, lime juice, chili powder, and salt to a blender or food processor. Pour in the cooled syrup and blend until silky smooth. Taste and adjust lime juice or chili powder as desired.
03 - Transfer the mixture to an ice cream maker and churn following the manufacturer's directions until thick and creamy, approximately 20 to 25 minutes. If no ice cream maker is available, pour the base into a shallow freezer-safe container and freeze for 4 hours, stirring vigorously every 45 minutes to break up ice crystals.
04 - Spoon the churned sorbet into a lidded freezer-safe container and freeze until firm, about 2 to 3 hours.
05 - Remove from the freezer and let rest at room temperature for 5 to 10 minutes to soften slightly. Scoop into bowls and serve immediately. Garnish with fresh mint or additional lime zest if desired.
