01 - Pour the chilled lemon-lime soda, pineapple juice, and fresh lime juice into a large punch bowl. Stir gently to combine without losing carbonation.
02 - Use an ice cream scoop to distribute rounded scoops of lime sherbet across the surface of the punch.
03 - Allow the mixture to rest for 2-3 minutes, giving the sherbet time to soften and create a frothy, layered effect on top.
04 - Gently stir once or twice with a ladle to swirl the melting sherbet through the punch, creating a marbled appearance.
05 - Float fresh lime slices and mint leaves on top. Serve immediately in chilled glasses while the sherbet is still frosty.
