And somewhat easy to find in the SF Bay Area, Los Angeles, Las Vegas, and I would guess New York, but certainly far more expensive than in South America.
Acaí has been a staple bougie food in america for at least twenty years. I suspect you can find it in every major city in america.
I was under the impression that it's different in south america, it can be savoury sometimes?
Not that I know of. However, the “slurpie” style with fruit/granola from Rio that went out to the world, is good but the smooth version from the North with tapioca is better. Almost like a light pudding.
Yeah the people living in the Amazon, where açaí is from, eat it with fried fish and they call the açaí bowl "sorvete de açaí", açaí icecream
