I have a hard time finding nice, fresh fruit with no testa. One thing that will kill acceptance of a fruit dead in its tracks is wood in the flesh. Too bad there are so many crap ones on the market, as the good ones are pretty damn good. As a side note, a friend who lives on the other side of town tells me there is a 'rambutan farm' in Brisbane. Someone planted out a whole heap of trees a few years back. They have not grown an inch - though they havent died, so they are doing better than I would have thought. Who knows, maybe one of them will decide to grow and spawn the first cold tolerant rambutan - but for now its just a stand of trees to giggle at.
