Taste the blended mixture and adjust the sweetness or acidity if desired. Pour the mixture into a mixing bowl.
Transfer the bowl to the freezer. Every 30 minutes, use a spatula to scrape and stir the mixture to break up ice crystals and promote even freezing, repeating this process 2-3 times until the sorbet is firm but scoopable.
Once the sorbet reaches a smooth, dense, and icy consistency, scoop into serving dishes. Serve immediately for a soft texture or freeze for an additional 30 minutes for a firmer finish.
Garnish with fresh mint or lime wedges if desired. Enjoy the refreshing, icy treat.
