In a medium saucepan, combine the sugar and water over medium heat. Stir until the sugar has completely dissolved to create a simple syrup. Once dissolved, remove from heat and let it cool.
While the syrup is cooling, wash the raspberries and place them in a blender. Add the fresh lemon juice and lemon zest. Blend until smooth.
Strain the raspberry mixture through a fine mesh sieve into a large bowl to remove the seeds, pressing gently with the back of a spoon to extract as much puree as possible.
Once the simple syrup has cooled, combine it with the raspberry puree in the bowl. Mix well to combine.
Pour the mixture into a shallow dish or ice cream maker. If using an ice cream maker, follow the manufacturer’s instructions for churning. If using a shallow dish, place it in the freezer. Stir the mixture with a fork every 30 minutes for about 3-4 hours until it reaches a fluffy, sorbet-like texture.
Once the sorbet is ready, scoop into serving bowls and garnish with fresh mint leaves if desired.
Notes
Garnish with fresh mint leaves for an extra touch.
