There exists a berry (native to West Africa) that, when eaten, makes anything bitter eaten within a few hours after OUTRAGEOUSLY SWEET!!!! Sour lemons? Try Miracle Fruit. It has been on my radar some time and I (desperately?) want to give it a try. It has the novelty of breathing helium or optical illusions. I like things that mess with my senses (WITHOUT the use of illegal substances thank you). It is mentioned in the kitschy book “Fruit Hunters” by Adam Gollner. It will likely come out first in its most lucrative market for artificial sweeteners (all us obese North Americans who want to have our cake and eat it too, without it going straight to our guts, thighs or working out). Other potential uses: making food appealing again to cancer patients thus helping them to recuperate some strength and nutrients. Diabetics. What a funky berry!
