After 5 months in Brazil, I spent a few days in California in August, split between a visit to Yahoo! Research (they gave me some money for my research, which was very nice), and a couple of days in SF to catch up with friends. While there I got to try the “miracle fruit” – something I read about in some blog or something like that (perhaps in Wikipedia). It’s a small dry fruit, which you chew on, and then anything you eat tastes sweet. We experimented with things like lemons and vinegar. It was the best vinegar I ever drunk, I must say.
