I'm looking for Guanabana fruit--aka Chermoya. It has a white flesh and black seeds, yields a juice that is sort of milky looking. Green on the outside, shaped like a large (melon-sized) green spiny strawberry.
I haven't seen it anywhere around here--just in S./Central America. Anybody seen it at a local grocery/market? Maybe one of the Korean ones? It is of southeast asian origin, I believe. I seem to be seeing more tropical melons, but not this one.
