I don't want to keep you guessing, so I'll tell how it works. Contrary to popular belief the effect isn't magic or even a divine intervening, as far as I know, what I do know is that there is a large glycoprotein chain called Miraculin. Miraculin isn't just any protein chain, in fact it was so large scientists had a hard time finding it, ironic but its the truth. When the miraculin is consumed it binds to the taste buds and is activated by acidic/bitter foods, releasing sugars onto your taste buds, creating the pleasurable sensation which is Miracle Fruit.
