According to youtube video comments Jackfruit is King over Durian but then I suspect the reason being many have yet to try Durian or a Excellent variety of Durian that would make them rate it higher.
Well according to Thai marketprices for Durian and Jackfruit the Durian is the absolute winner with 500us$ for a top notch durian versus maybe 50us$ for the best jackfruit.
And for jackfruit most vendors have inferiour fruit for sale, they don't taste anything like the best ones but they all are the same price. I only eat jackfruit from 1 vendor who always has excellent quality or she won't even sell jackfruit. No idea why this vendor always has far better fruit than all the other ones, they might have their own orchard.
And nope, we don't need the whole world to eat jackfruit or durian. Since Thailand exports durians the prices are higher and the fruits smaller. Now it's almost impossible to find a big durian in Thailand cause the chinese have bought ALL the big ones. Same goes for mangosteen.
And for durian it freezes very well, they should just blend the durian flesh, put it in icecream bowls and export it. That's how i make durian icecream, i buy the soft ones (which the Thai don't like) for half price and blend them all with a tiny bit of salt, nothing else. That's perfect icecream and tastes exactly the same as the overripe durians..mind you, for a Thai EVERY tree fallen durian is overripe, they like them a tiny bit underripe while they are still crunchy on the outside and soft inside.
