01 - Combine the sugar and water in a small saucepan. Heat over medium, stirring constantly until the sugar has fully dissolved. Remove from heat and let the syrup cool to room temperature.
02 - Place the cubed mango, coconut cream, lime zest, lime juice, chili powder, and a pinch of salt into a blender or food processor. Pour in the cooled simple syrup.
03 - Blend on high until the mixture is completely smooth and velvety. Taste and adjust the lime juice or chili powder to your preference.
04 - 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 an ice cream maker is unavailable, pour the mixture into a shallow freezer-safe container, freeze for 4 hours, and stir thoroughly every 45 minutes to break up ice crystals.
05 - Transfer the churned sorbet to a lidded freezer-safe container. Freeze until firm, about 2 to 3 hours.
06 - Remove the sorbet from the freezer and let it sit at room temperature for 5 to 10 minutes to soften slightly. Scoop into bowls or cones and serve immediately. Garnish with fresh mint or additional lime zest if desired.
