In a medium-sized saucepan, combine the granulated sugar and water over medium heat. Stir continuously until the sugar has completely dissolved, forming a simple syrup. Once dissolved, remove the saucepan from the heat and allow the syrup to cool to room temperature.
While the syrup cools, take a blender and add the fresh raspberries, lemon juice, lemon zest, and the cooled simple syrup. Blend on high until the mixture is smooth and all ingredients are well combined.
Using a fine mesh strainer, pour the blended raspberry mixture into a large bowl. This will help separate the seeds from the liquid. Use a spatula to gently press the mixture through the strainer to ensure that all the flavorful juice is extracted.
After straining, cover the bowl with plastic wrap or a lid and place it in the refrigerator. Let it chill for about 1 hour to enhance the flavors and cool down the mixture.
Once chilled, pour the raspberry lemonade mixture into an ice cream maker. Follow the manufacturer’s instructions to churn the mixture until it achieves a soft-serve consistency, usually about 20-25 minutes.
After churning, transfer the sorbet into a lidded airtight container. Freeze for a minimum of 4 hours, or until the sorbet is firm.
Just before serving, allow the sorbet to sit at room temperature for a few minutes. This will soften it slightly, making it easier to scoop.
Notes
For an elegant touch, serve the sorbet in stylish dessert bowls. Garnish each serving with fresh mint leaves and a few whole raspberries on top for a vibrant burst of color and freshness.
