This is the coolest thing I have ever seen and tried. It's a small fruit found in west Africa. Once eaten anything eaten subsequently with a sour or bitter taste will taste sweet. Yes it does work. My friend let me try one berry and it's crazy. Because of its miraculous way of making things taste so good, the active protein found in the fruit was dubbed miraculin. A person has receptors on their taste buds that identify sweet, sour, bitter and savory tastes. Normally, if you were to eat a lemon or a lime, your sour receptors would start firing. But once you've eaten a miracle berry, however, the sweet receptors start signaling and suppress the sour tastes. The miraculin rewires the sweet receptors to temporarily identify acids as sugars. I've got to see what the chemical structure of this miraculin looks like.
