When I want instant “vacation energy” without leaving the couch, this is what I make. It is bright, pineapple-forward, and takes almost no effort.
For a more layered, grown-up flavor, add a small splash of alcohol-free spirit before topping with sparkling water. If the drink tastes too sweet, squeeze in extra lime. If it feels a little flat, use very cold juice and sparkling water so you do not need too much ice and the flavor stays strong. This one scales easily for friends and fits right into your easy, tropical hosting routine.
