Rattan Fruit or Littuko is a rarity in Southeast Asia. I've traveled all over the region and hardly see the "fruits" in abundance. It's scaly, as though they come from snakes or some other reptile. You peel them like you do with lansones and out pops a triumvirate of clustered pods with the sourest taste this side of Datu Puti. While I love fruits, these are another matter.
I'd probably acquire the taste after a hundred pieces. But allow me not to wait for a hundred.
This is the Eye in the Sky!
