"Poi is a Hawaiian word for the primary Polynesian staple food made from the corm of the kalo plant (known widely as taro). Poi is produced by mashing the cooked corm (baked or steamed) to a highly viscous fluid. Water is added during mashing and again just before eating, to achieve a desired consistency, which can range from liquid to dough-like (poi can be known as two-finger or three-finger, alluding to how many fingers you would have to use to eat it, depending on its consistency).

Poi should not be confused with Tahitian po'e, which is a sweet, pudding-like dish made with bananas, papaya, or mangoes cooked with manioc and coconut cream. The bowl of poi was considered so important and a sacred part of daily Hawaiian life that whenever a bowl of poi was uncovered at the family dinner table, it was believed that the spirit of Hāloa, the ancestor of the Hawaiian people, was present. This is because Hawaiians believed that the taro plant, or kalo, was the original ancestor of the Hawaiian people. Because of that, all conflict among family members had to come to an immediate halt ... Most first-time tasters describe poi as resembling library paste - more an allusion to the texture than the fruit, which is delicate. The flavor changes distinctly once the poi has been made. Fresh poi is sweet and edible all by itself. Each day thereafter the poi loses sweetness and turns slightly sour. Because of this, some people find poi more palatable when it is mixed with milk and/or sugar, although purists frown on this. The speed of this fermentation process depends upon the bacteria level in the poi. The bacteria are harmless, and some would even say beneficial. To slow the souring process, poi should be stored in a cool, dark location (such as a kitchen cupboard). Poi stored in the refrigerator should be squeezed out of the bag into a bowl, and a thin layer of water drizzled over the top to keep a crust from forming. Sour poi is still quite edible with salted fish or lomi salmon on the side. Some would reasonably argue that poi is inedible beyond five days. Sourness is prevented by freezing or dehydrating, although the resulting poi tends to be bland in comparison with the fresh product ..." (Wikipedia)
