I hope you hear me out on this one and don't just accuse me of creating disgusting concoctions before closing your browser. I would also like to clear up that I am not a recovering alcoholic and am therefore restricted to drinks of the non-alcoholic kind. I like a trip to a cocktail bar as much as the next person, but I just couldn't resist trying this when I heard about it.
I filled the glass half full with ice, added two teaspoons of balsamic vinegar (but apparently any vinegar is fine) and topped it up with lemonade. I guess it's to your own preference what measures you use though, if you want it to be more like cream soda and sweet use less vinegar, if you want it to be more like a glass of Pimms add more vinegar.
This is a new favourite of mine, perfect for barbecues and garden days. The science behind it is that lemonade on it's own doesn't quench your thirst because of all the sugar in it, but this does because of the added sour note. Clever eh!
