In a medium saucepan, combine the sugar and water over medium heat. Stir until the sugar is completely dissolved to create a simple syrup. Once done, let it cool for a few minutes.
Meanwhile, in a food processor or blender, add the fresh raspberries and blend until smooth. Strain the mixture through a fine mesh sieve to remove the seeds, pressing down with a spatula to extract as much puree as possible.
In a large mixing bowl, combine the raspberry puree, lemon juice, lemon zest, and a pinch of salt. Pour in the cooled simple syrup and stir until well combined.
Transfer the mixture to an ice cream maker and churn according to the manufacturer’s instructions until it reaches a soft-serve consistency.
If you don’t have an ice cream maker, pour the mixture into a shallow dish and freeze for about 2-3 hours. Stir the mixture every 30 minutes with a fork to break up ice crystals until it’s firm.
Once the sorbet is frozen to your liking, remove it from the freezer and let it sit at room temperature for 5-10 minutes before serving for easier scooping.
Notes
Serve the sorbet in chilled bowls or ramekins, garnished with fresh raspberries and a sprig of mint for a refreshing touch.
