great post Adam.
whats parking lot fruit?
i would have added passion fruit to the list but apaprently it is better appreciated than I thought.
to an extent, all the best tropical fruits make this list in the western markets. People should be lining up on their bended knees to buy mangosteen, lychees, florida mangoes, jackfruit, marang etc, and instead, these fruits are, on the whole, only appreciated by us fruit nuts.
similarly, all the best varieties of temperate fruits are not sold commercially and herefore undiscovered by the average American idiot who happily buys and eats the tastless shiny flowery hybrids that the fruit markets sell.
but for a specific underappreciated, underutilized fruit, I would add marang to the list. Amazing flavor and fragrance. just has a very short shelf life once opened- would never be an issue for me!
