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