The "Dirty Soda" trend has taken the internet by storm, turning a standard Diet Coke into a creamy, tropical mocktail. Originating from the specialty soda shops of Utah, the "dirty" element comes from adding coconut syrup and heavy cream to the fizz. The acidity of the lime cuts through the richness of the dairy, resulting in a drink that tastes remarkably like a melted float but with a much lighter, zippier finish that won't weigh you down.
500ml Diet Coke (chilled) 1 tbsp coconut syrup (or sugar-free coconut syrup for fewer calories) 1 tbsp half-and-half or heavy cream Fresh lime wedges Plenty of pebble ice
Fill a large glass to the brim with pebble ice.
Pour the Diet Coke over the ice, leaving about an inch of space at the top for your dirty mix-ins.
Squeeze the juice of two lime wedges into the soda and drop the wedges in.
Add the coconut syrup and then slowly pour the cream over the top.
Watch the cream swirl through the dark soda for that perfect aesthetic, give it a gentle stir, and enjoy this creamy-yet-crisp viral sensation immediately.
