Petai beans are definitely something of an acquired taste...and smell (just like the King of Southeast Asian fruits called Durian). Highly popular in Southeast Asia, the beans are contained in long, flat green pods with bulging bumps in the shape of small almonds. Petai has a really peculiar smell that is dispelled through the urine (so, make sure the flush works!). As such, it is also nicknamed as 'stinky beans'. Petai is said to contain 3 types of natural sugar - sucrose, fructose and glucose. It is also believed to be carrying many beneficial medicinal values from regulating blood pressure to curing a hangover with a glass of petai milkshake (err, anyone up to this challenge?!).
