I'm in my hometown so we don't have dragonfruit here. When I go back to my work-city, I'll try the dragonfruit thing!
Thanks for the recco.
but I remember while travelling once in India in very hot bus one fellow traveller offered me watermelon with some spice which was very interesting flavor (as interesting as salted chocolate for instance) and good combination, but never figured out what spice they used, normally I don't like watermelon at all, but together with spice it was interesting combo, could never reproduce it again :-( it will be 20 years since my visit next year
