I’d be very surprised if that’s available here, although maybe there’s some equivalent East or Southeast Asian product that goes by a different name. I usually bring a few bags back from Canada - even in Vancouver, finding it was a minor quest.
It doesn’t seem to be on iHerb; even on Amazon, it’s “Currently unavailable”, or doesn’t ship to this location.
Paging @Dragonbones. If anyone knows, it’d be him.
EDIT: very thin ten-year-old hints in this thread; for what it’s worth, I don’t think I’ve ever seen it on the menu at the different Mexican restaurants.
