It's funny you should ask this. Yesterday I bought a fruit called a NONI. I saw it at the store and my friend walked in and said how good they were for you. I am waiting until it ripens to mix with pineapple in the blender and then drink 'just a bit of it'. I had never heard of it or seen it before.
Here in Brazil, there are lots of different things I have tried. A chuchu, a maxixi, and several fruits that you wouldn't see anywhere else.
