I had read about miracle fruit in the New York Times about a year ago, but yesterday was the first time I had ever seen it in a supermarket. Apparently, if you eat this berry, for about a half hour afterwards, any sour foods that you eat will taste incredibly sweet and delicious. I personally don't see the point of this, especially since I usually eat sour foods because I like the sour taste. The price is another factor that will keep me from trying it: 580 yen for one! Maybe they could reduce the price if they didn't over package the thing. Yes, that is just one tiny miracle fruit inside all that plastic. Even more amusing is how the price sign says one "pack" is 580 yen when you're not getting a pack of anything at all, just a lot of packaging!
