Trader Joe's now carries freeze dried mangosteen. Huh! I can report that while it probably tastes a lot better fresh, I suppose this will have to do until Thailand starts sending them our way. This version is kinda like a freeze dried strawberry in its overall flavor, with some tropical subnotes. Can't wait for the day when I can taste one for real.
(On a totally unrelated seasonal TJ's note - peppermint joe-joes are back!)
