I'd also like to mention Sapota.

Honorary mention to Grewia asiatica and Syzygium.

I've been meaning to look into planting some Camas bulbs. A kind of tuber crop grown by indigenous people around here. Used to be entire prairies of them before whitey showed up

Pakay! Also called ice cream bean. It's a giant bean, inside there's big seeds surrounded in white solid-fluffy stuff. You eat the white stuff. It's sweet without being overpowering and the consistency is interesting. Delicious

I don't see it mentioned so maybe it's not lesser known, but jackfruit is amazing. SEA like most amazing fruit but have seen it more often in North America. Fresh, not the prepped and sauced vegan style.

Rambutan

Maypops, which are a north american species of passionfruit. Obviously not a great hand fruit.

Persimmons. Have a full size tree about to drop maybe 40 pounds of them. And I have no idea what to do with that many.

Jujubes. They're like a dryer sweeter small apple. They don't need a lot to grow where I am and there's hundreds per tree.

So not in my area, but I recently discovered cloudberry jam, which is absolutely delicious. It's like a mix of citrus and strawberry.

Arum is an incredbibly underrated veg too, with an amazing texture.
