Asian Group

I first found out about it from a National Geographic. Waaay back in ?'79, or '80. It was quite an unknown quantity back then to the general public. Not quite so very well known, still, I think.
Origins- Malaysia, Indonesia, and Thailand. Expanded to a few more countries; Australia, Vietnam. Even Hawaii, and Puerto Rico.

Custard texture but it's been described as eating the most heavenly dessert standing in a garbage dump. Yeah. 😱 And several descrip did mention onions as a major conponent.

People either absolutely love it, or abhor it! (More divisive than Trump!)
In a hotel a patron got busted for eating it in their room (air ducts). Special dogs on a Japanese Airline going to fly from Malaysia found a passenger with a super cellophaned wrapped, and newspaper covered one on their carry on.

I saw some in Chinese fruit stand in Chinatown in the '90's. Almost shocking bc if it's reputation!
