The difficulty lies in the fact that everything is relative to where you are and what is available. I have eaten many things that most Americans have never tried and most would NOT try, but I would only classify a few as gross. And while you might think eating live worms is an exotic dish, in the jungle it was merely fast food!
I have eaten goat, which I do not considered gross, especially when prepared in a coconut sauce. Pigs stomach, tripe, would be my personal choice for the one of the grossest thing I have had to eat overseas. Or maybe intestines cooked while containing half digested food. This delicacy was once served to us by a church congregation as we were seated in the center and everyone else stood and watched us eat. I had a hard time getting it down without showing disgust on my face. It was served us in love and I tried to think of all that love as I chewed and swallowed, breathed deeply through my nose, chewed and swallowed. That meal took the most effort of anything I have ever attempted, including natural childbirth!
I have also eaten monkey, but unless it is smoked whole, it is fine. It tastes fine even when smoked but it does resemble a small child and...well, you can imagine.
Then there are the rodents we ate in the jungle, including the world's largest rodent, the capybera, but they are quite tasty and make a good home made breakfast sausage as well. However, the wild boar is delicious!
Grub worms are not too bad, very greasy, but they fry up nice and crisp, sort of like bacon. Earth worms are best eaten smoked, so if ever asked your preference, remember, go for the smoked, not the raw or live worms. Think you can remember that?
Then there are the insects. Termites, ants and such are common in hot sauces and really add no taste just a bit of texture, so it's all good! I have not eaten tarantulas myself, but they are said to taste like shrimp!
I've eaten gator which is quite tasty. I even tasted jaguar, which grosses out the Ye'kwana indians. I never ate snake but I have watched it be eaten with relish by indians. It seemed yucky, but who knows?
Since living in Paraguay, I can not recall eating anything too exotic. Some of the food is great, some is bland, but it is all quite edible. I think the worse food I have had here was a hamburger served to me at Burger King in Asuncion. So far anyway...
I easily can recall the most exotic (gross) food I have ever had to eat in my life. It was when my grand mother made me eat pickled pigs feet once while visiting her in West Virginia!!!!
What is the most 'exotic' food you have ever eaten?
