We had a chance to eat salt-pickled palolo in East Timor, which are reproductive organs of marine worms detached into the sea. Once a year, the local people go to beaches and collect palolo floating in the sea on a full moon. It is considered as a seasonal treat and tastes like raw oyster. In reality, it is in vivid greenish blue unlike in the photo. Actually, we had this opportunity because of a staff of a guesthouse we stayed at, who kindly brought us a bottleful of palolo from her house even though we were slightly late for the season.
The local guide in East Timor brought a toddy palm fruit (Borassus flabellifer) (left) and the kernels inside the fruits (right) for us. The yellow fibrous part is slight sweet like pumpkin. The kernels are juicy and gelatinous and have little taste. The white layer covering the kernels is bitter, but the East Timorese don't seem to mind it.
We tasted yellow jujube fruits (Ziziphus sp.) in East Timor. The local guide disappeared into the bushes and came back with these fruits in his hands. They tasted slightly like apple and were very sour.
