In Bali we had the chance to see a coffee plantation where they told us about their special coffee. The Palm Civet (a wild cat-like creature thingy) wanders around and eats the coffee beans, and the bean ferments in its stomach for a few days. Then when it comes out, people go round and collect the poo and make it into coffee. How people discover these things is beyond me, but I'll try anything once!
It cost a fortune - that jar costs 25 USD, I got just the one cup which cost me 30,000 Rupiah - about £2. And yup, it was good. Not sure I'll be making a habit of drinking it though.
