I recall reading somewhere that the fruits we get in our local
supermarket represent only a fraction of a percent of all the fruits
available in the world. Furthermore, the fruit we do get are chosen
not because of their taste but more so because of their low price from
large economies of scale.

So how would one go about sampling all the infinite varieties of
exotic fruits that exist in the world? I'm sure there must be some
truly delicious ones out there that we've never heard about!

I'm surprised nobody has thought of opening a fruit bar that only
sells exotic fruits. Sure the price would be high, but fish is flown
in from all over the world and that is not terribly expensive. Plus
fish is a lot more perishable than fruit.
