Parkia speciosa

Parkia speciosa, the bitter bean, twisted cluster bean, sator bean, stink bean, or petai is a plant of the genus Parkia in the family Fabaceae. It bears long, flat edible beans with bright green seeds the size and shape of plump almonds which have a rather peculiar smell, similar to, but stronger than that of the shiitake mushroom, due to sulfur-containing compounds also found in shiitake, truffles and cabbage.
