01 - Combine sugar and water in a small saucepan over medium heat. Stir continuously until sugar completely dissolves, approximately 2-3 minutes. Remove from heat, add mint leaves, and steep for 10 minutes. Strain syrup to remove mint leaves.
02 - Add raspberries, lemon juice, lemon zest, and mint-infused syrup to blender or food processor. Blend until completely smooth and uniform in texture.
03 - Pour blended mixture through a fine-mesh sieve to remove raspberry seeds. Press firmly with a spoon to extract maximum liquid while discarding solids.
04 - Stir in vodka if using. This ingredient prevents sorbet from freezing too hard and improves scoopability.
05 - Transfer mixture to shallow freezer-safe container. Freeze for approximately 4 hours, stirring every hour with fork to break up ice crystals. Continue until firm but scoopable.
06 - Scoop into chilled bowls or glasses. Garnish with fresh mint leaves and serve immediately.
