The "miracle fruit" (Sideroxylon dulcificum if you want to get all scientific about it), is a cranberry-sized West African berry that that numbs your sour and bitter tastebuds for a couple of hours after eating it. That means that everything that used to taste sour now tastes sweet. After eating one stout beers taste like chocolate milkshakes, grapefruits taste like pixie sticks, cheeses taste like frosting, it will make even the crappiest tequila taste like lemonade.
The freeze-dried tablets are really hard to get outside of Asia, but I am fully interested. If anyone is here from Asia and could send me some, I'll pay you for it.
Seriously.
Do it.
