This sparkling punch from Ron Cooper's book Finding Mezcal was inspired by a cocktail called the Oaxacan Dream, made by Steve Olson, Leo DeGroff and Andy Seymour. "It was so simple, yet so beautiful—mezcal, pineapple juice, cranberry, lime, and agave nectar, but the juice was freshly pressed and the drink came with a grilled pineapple garnish," says Cooper of the original cocktail. "We loved the drink, but after a few years, it began to feel pretty basic compared to the amazing cocktails bartenders around the country were coming up with. So, Steve did what any rational bartender would do: He turned it into a punch."
