About Vietnam's durians (Sầu riêng): 

Five or six times larger than the mango, durian is unique fruit with the thick and rough skin, covered with sharp thorns. At first, one may find durian’s smell extremely unpleasant (to the extent that most airlines have to ban passengers from carrying this fruit on board). Yet if you can eat it, you will love it. 

Just after cutting the edge of the outer sell gently, one will be fascinated by layers of bright yellow segments of meat shining like butter. It has the special flavor of well-kept honey and rich in nutrition. “Smell like hell, taste like heaven”, that is what they talk about durians.
