Yeah, force of habit. Never heard of jackfruit until HN where we get an article about them every few months as people discover them.
Two other fruits I think more Americans should try are guyaba/guava and guanabana. Both are somewhat annoying to eat due to the seeds, but they have some unique flavors. Those are my two go-to icecream flavors.
Unfortunately the lack of demand makes them expensive in the US where I was astounded. They almost give them away where I live in Mexico.
Same with dragon fruit. A single fruit was $8 in Texas. Meanwhile I get them from the pitaya guy who rolls down my street 4x for <$1.
