Rambutan

I am really on a roll with all these exotic fruits recently! Yesterday, after lunch, we knocked some ripe Rambutans (also called Mamon chinos here) off a tree that is absolutely full of them.
These fruits are related to lychees, but aren't as good (in my opinion -- lychees are one of my favorite fruits!). These rambutans look like little red spiny urchins (but they aren't sharp) and once you open the fruit, you see the ovoid seed inside covered with shiny squishy pulp. The taste reminds me of a sour green grape, but I like it.
