Origins: Alas, there is no delectable blue fruit that grows in Japan, causes "flavors to switch" after you eat it, and costs about
However, there is a real "red miracle berry" fruit (Synsepalum dulcificum) that produces a protein known as "miraculin" which can cause other sour foods subsequently consumed to taste sweet:
The berry and its plant (Richardella dulcifica) grows in West Africa. While the local population has been using its miraculous properties for centuries, it was only in 1968 that the all-important protein miraculin was extracted and sold in tablets. They’re now available the web and often feature in "taste tripping" parties where brave souls dine on pickles and limes.
The miraculin also toys with sweet, sugary food in interesting ways. Drop a load of aspartame after popping a miracle berry tablet and the miraculin represses your sweet receptors, making sweet foods taste bland. But in a slightly more acidic environment, the receptor’s response skyrockets, making aspartame taste sweeter than ever though possible.
