Fruit Leather. Like no one knows about this delicious meal item. It's like "fruit by the foot", which is the cheap sugar-laden horrible knock-off, but better. You can get organic versions of it too. It usually comes in 4"x2" strips, but you can make your own- the process is easier than jam and jelly from what I understand.
Also out of my group of friends, no one really knows about a lot of land-history, like what kind of soil is underneath NYC in what shaped it's skyscrapers we see today... Or that people whine and moan about east Texas being so humid because it's "near the equator!!" and my response is "You do realize it was a swamp before we were able to modernize it and live there, and the invention of the A/C units...blah blah blah cool history stuff tangent"
