Interesting that Caipirinha seems to be somewhat exotic in the US. In Germany is has become very fashionable a couple of years ago, and by now it’s pretty much a cocktail staple. It’s pretty popular with girls, so that might be good to know for dates.
Right now I like a mixture of equal parts Bombay Sapphire and Rose’s lime juice, filled up with Tonic. For summer I am looking forward to the Mojito.
