Bertie Bott's Every Flavor Beans
Definitely not for the faint of heart or weak of stomach.
They are infinitely more fun when eaten with company, since you'll take a bite of one, and want to see your friends' expressions as they partake of the utter grossness of some of the flavours included in the box. You also want to have some kind of beverage to clear your palate. (I had beer.)
Black Pepper: Since actual black pepper was listed on the ingredients, this was very realistic and had a nice spicy zing.
Booger: Salty, just like you remember.
Dirt: Tastes just like Demeter's Dirt perfume smells.
Ear Wax: I suppose this tasted like ear wax. Vaguely citrusy with weird aftertaste. But I've never tasted ear wax. Have you?
Grass: Herbal, like a freshly mowed lawn.
Sardine: Disgustingly fishy but very accurate.
Spinach: Also very true to reality, due to actual spinach paste content.
Tutti-Fruitti: It resembled the tutti-fruitti bean on the Flavor Guide, so that's what flavour I'll assume it was. But OH GOD IT WAS FUCKING DISGUSTING. It tasted exactly like week-old spaghetti that had absorbed the flavours of everything else in your refrigerator.
Vomit: Nowhere near as bad as I expected. When I bought the box of beans, the guy at the candy store (appropriately called Suckers) asked me if I was sure I wanted to try them. I think vomit is a very personal thing. No one else's puke should taste the same as mine, dammit!
Suggested flavours for Jelly Belly: grass (the non-lawn variety), beer, shit
I give it /5 for the taste and /5 for the entertainment factor.
