Add all ingredients to a cocktail shaker with crushed ice. Briefly shake to incorporate the ingredients, then pour into a large rocks glass. Top with more crushed ice, and garnish with a mint sprig.
Verdict
Refreshing and light. All the components come through, without anything dominating. The absinthe spritz on top is a fitting touch. The crushed ice might make it a bit too watered down. Consider going with ice cubes instead.
