01 - Combine the sugar and water in a small saucepan. Heat over medium, stirring constantly until the sugar fully dissolves. Remove from heat and let the syrup cool to room temperature.
02 - Add the mango cubes, coconut cream, lime zest, lime juice, chili powder, salt, and cooled sugar syrup to a blender. Blend on high until completely smooth and creamy. Taste and adjust the lime juice or chili powder as desired.
03 - Pour the blended mixture into 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 the mixture into a shallow freezer-safe container and freeze for 4 hours, stirring vigorously every 45 minutes to break up ice crystals.
04 - Transfer the churned sorbet to a lidded freezer-safe container. Freeze until firm, about 2 to 3 hours.
05 - Remove the sorbet from the freezer and let it sit at room temperature for 5 to 10 minutes to soften slightly. Scoop into bowls and garnish with fresh mint or extra lime zest if desired.
