How to Make It
In a pitcher, stir together the passion fruit puree, sugar and lime juice until the sugar is dissolved.
Stir in the vodka. Fill 6 tumblers with the ice and pour the drink over the ice. Garnish with the lime wheels and serve.
Frozen passion fruit puree is available at specialty food shops. Vergera Boiron is a terrific brand. In a pinch, substitute passion fruit sorbet and reduce the sugar in the recipe.
