Start by preparing a simple syrup: In a medium saucepan, combine the granulated sugar and water. Place the saucepan over medium heat. Stir the mixture constantly until the sugar has fully dissolved, creating a clear syrup. Remove from heat and allow it to cool for about 5-10 minutes.
While the syrup cools, prepare the raspberry puree: Place the fresh raspberries in a food processor or blender. Blend them until the mixture is smooth. To ensure a seedless puree, strain the blended raspberries through a fine mesh sieve into a bowl, using a spatula to press the mixture and extract as much puree as possible.
In a large mixing bowl, combine the strained raspberry puree with the freshly squeezed lemon juice, lemon zest, and a pinch of salt. Pour in the cooled simple syrup and stir well to ensure all ingredients are fully integrated.
If you have an ice cream maker, transfer the raspberry-lemon mixture into the machine and churn according to the manufacturer’s instructions until it reaches a soft-serve consistency.
For those without an ice cream maker, pour the raspberry mixture into a shallow dish suitable for freezing. Place the dish in the freezer and allow it to freeze for about 2-3 hours. Every 30 minutes, use a fork to stir the mixture vigorously, breaking up any ice crystals that form, until the sorbet is firm yet scoopable.
Once your sorbet reaches your desired level of firmness, remove it from the freezer. Let it sit at room temperature for 5-10 minutes before serving; this will make it easier to scoop.
Notes
Serve in chilled bowls or ramekins, garnished with fresh raspberries and mint.
