I was in Montreal last weekend and found some of these, so maybe there is some hope that they might be available somewhere in New York. I am a frequent visitor of ethnic groceries in all parts of the city and I haven't seen these here yet in NYC. I'm looking for FRESH (not canned, frozen, etc.)
rambutan (these 3 were available in Montreal)
jambu (seen these in Vietnamese stores in No. Va. but never here in New York).
Please try to be specific: "look in Chinatown/Flushing" is no help at all.
