Lime Salt Rim: In small dish, combine salt and lime zest. Rub rim of each serving glass with lime wedge, then dip in salt mixture.
Margaritas: Add passion fruit nectar, coconut water, tequila, lime juice and orange liqueur to an ice filled pitcher; stir to combine.
Pour into glasses; serve immediately.
Note: Alternatively, omit salting the rim, and add a pinch of sea salt to the margarita mix.
