Wait what? I grew up in Miami and ate mangos off the tree. I've also had store bought mango and Ataulfo (Champagne) mangos from Mexico. I don't think I'm missing anything with the store bought mangos. So I think that's a bad example.
But, there's a variety of pineapple you can only get only in Hawaii that's way better. And I've only ever sourced really good key limes from friends and family trees in Florida.
Store bought tomatoes are also usually shit, but you can get ones from the farmers markets and road-side stands.
I can't specifically speak to mangoes since I haven't tried them in that many places, but melons in the United States are outright terrible in comparison to anything I had when I lived in Japan. They cost more but you're pretty much guaranteed quality. A relatively inexpensive melon in Japan might be about 10 bucks but its going to be as good as the best melon you can get in the crap shoot at the grocery store. When you start moving up in price the melons basically become so good that they are an out and out replacement for any kind of high end dessert. Theres no need for ice cream, yogurt, honey, etc because the melon is just that good.
What kind of melon? We have fantastic watermelon here if you get it in-season and local and I've been pretty happy with cantaloupe and honeydew. A lot of problem is Americans have no clue what in-season fruit is and don't buy local.
NC has a bounty of fruit and vegetables available locally grown:
I miss fruits in general in japan. It’s one of those things I’m willing to pay a premium for because they are just that much better. I can’t eat honey dew and cantaloupe in the states anymore.
Eat a mango from India or Pakistan (in the summer) before you die. Hard to find in the US unfortunately, but you'll realise that the mangoes you're familiar with taste like tree bark.
