Up until recently, mangosteen was illegal to import into the United States. When I first moved to the U.S. from Canada, no one understood what I was inquiring after when I asked grocery stores if they carried this superfruit. In Vancouver, British Columbia, where I grew up, mangosteen can be bought at Asian grocers or large markets like the popular Granville Island, where I often bought this delicious fruit for special occasions. Where I first found out about them, in Tahiti, mangosteen is sold like green juice is in the U.S.
