Here's the NY times article and apparently this was also a feature on CSI.
Basically the miracle berry makes sour foods taste sweet. You just get the miracle berry on your tongue and it changes the way your taste buds perceive sour flavors for between 15 minutes and 2 hours (our effects lasted about a half hour.)
So I got a bunch of recommended tasting items together and talked some co-workers into tripping with me today at lunch. The limes were the best. They tasted like limeaid. Also good were the lemons, grapefruit, tomatillos, salt & vinegar potato chips, pickles, salsa, and kimchi. The red pepper hummus was good, but weird and almost fizzy? The spicy things were still spicy despite other accounts of the spicy not being hot. I like hot foods, but the jalapeno still packed the punch of jalapeno even without the seeds.
The hot stuff. Still spicy, just tastes sweeter. I thought the sundried tomatoes tasted like dried apricots, but everyone else said just tomato. And I usually like umeboshi, but it was sweet and even weirder than usual.
Lemons and limes were the favorite.
So all in all an interesting experience. If I get my hands on the real berries, I'll have to try this again. Makes for a fun party, even if it's at the office.
