Swiss lemonade or limonada suíça is a thirst-quenching, lime-based drink that hails from Brazil. In its basic form, it is made with fresh limes, water, sugar, and ice. The limes are usually cut into small pieces—with the skin on—and all the ingredients are shortly blended until frothy.
The drink should be served immediately, while it is still ice-cold. The most popular variation includes condensed milk, which provides a smoother and creamier texture. The unusual name of this limeade has never been completely clarified, but several theories suggest that it might have been invented by a Swiss restaurateur or at a Swiss hospitality school.
