You're likely to smell durian, long before you see it. Plenty of people tend to be averse to its strong smell and decline the opportunity to try it, but this tropical fruit is packed with nutrients. This fruit is often dubbed the 'king of fruits in South Asia' and is a must-try. The outside of durian is mostly green, with spikes and the inside consists of custard-like flesh with large seeds. In Thailand, you'll find many versions of Durian, and even durian chips, durian candy and dehydrated durian to try if you're not ready to try the fresh fruit straight away!
