After reading an article earlier, they are just little tablets called miracle berries and they makes pretty much all food taste sweet. I cant post the link on my phone but people pretty much call it "food-tripping". Being a typical stoner, i wonder how amazing it would be to take a tablet, get stoned and eat.
Yes, I've heard of them - synsepalum dulcifium is the name of the berry, or the plant anyways. I'd like to actually get a small bush/tree going myself - the stuff kind've costs a lot to get your hands on. When I was looking into it, I see that people (mainly int he states) actually host parties where a selection of interesting foods from sweet to sour to savoury is on offer. Apparently it's really good for chemo patients as well, not only does food taste a little "nicer" but chemo has been known to put shitty flavours in your mouth...this supposedly takes that away. Yeah, it's a very interesting fruit...yet to try it myself.
