Avaliable from firebox, just read their description and be amazed!
“Made from natural berries native to West Africa, these taste-twisting pills contain a rogue glycoprotein molecule (whatever that is) that binds to the tastebuds causing sour things to taste sweet. Simply pop one on your unsuspecting tongue, wait for the freeze-dried jungle juice to work its magic and prepare to be astounded. Lemons taste toffee-ish, vinegar tastes treacly and Guinness tastes like a stouty, chocolately shake. Even sprouts seem fruity. Eat something sweet and it’s like a sugar volcano erupting in your gob. Incredible!”
All i can say is…awesome.
