01 - Combine sugar and water in a small saucepan over medium heat. Stir constantly until sugar completely dissolves, approximately 2-3 minutes. Remove from heat, add mint leaves, and let steep for 10 minutes. Strain syrup to remove mint leaves.
02 - Place raspberries, lemon juice, lemon zest, and mint-infused syrup in a blender or food processor. Blend until completely smooth and uniform in texture.
03 - Pour blended mixture through a fine-mesh sieve into a clean container. Use a spoon or spatula to press mixture through sieve, extracting as much liquid as possible while removing raspberry seeds.
04 - If using, stir vodka into strained mixture. This ingredient helps prevent sorbet from freezing too hard and improves scoopability.
05 - Transfer mixture to a shallow, freezer-safe container. Freeze for approximately 4 hours. Every hour, remove from freezer and stir vigorously with a fork to break up ice crystals. Continue until firm and scoopable.
06 - Scoop sorbet into chilled bowls or glasses. Garnish with fresh mint leaves before serving. For best texture, let sit at room temperature for 2-3 minutes before scooping.
