Petai

Parkia speciosa is a tall, bat-pollinated tree from the Asian tropics.  The seeds of this species, know locally as petai, are combined with chili paste, garlic, and dried shrimp to make a variety of tasty sauces and curries.  The downside of eating petai is that it changes the color of your urine to dark brown and makes it smell really horrible for several days.  This can be a bit shocking if you are not expecting it.  The English name for Parkia speciosa, quite approriately, is stink bean. [NOTE: The Parkia seeds shown above were photographed prior to purchase in Pontianak, West Kalimantan.]
