Like so many great British beverages, tonic water got its start as a preventative measure against malaria. Fun fact: Quinine (the malaria-fighting ingredient) makes tonic water glow under blacklights! Make sure the variety you buy actually contains quinine, and isn’t made with high-fructose corn syrup. These days, you can even get your own high-quality tonic syrup and mix it with sparkling water to make excellent tonic water on-demand.
