This is a fruit called Monstera deliciosa.

The Monstera deliciosa fruit takes nearly a year to ripen, and only when it's fully ripe can it be eaten. It has a very unique flavor, resembling a combination of banana, pineapple, and mango.

Monstera deliciosa is the name of a fruit that is still quite unfamiliar to many people. It looks like an ear of corn that we commonly eat. It originates from temperate regions such as Central America or islands near the equator like Hawaii, Seychelles, Ascension, and the Society Islands.

The name Monstera deliciosa comes from two English words: "Monster" and "Delicious." The reason it's called "monster" is that this fruit contains a lot of oxalic acid when unripe, and this toxin can cause burning pain upon contact. Most of the toxin is concentrated in the hexagonal, honeycomb-like outer scales. If one tries to eat this strange fruit while it's still green, it can lead to poisoning.

Research shows that the Monstera deliciosa fruit is quite toxic when unripe. In fact, all parts of the Monstera deliciosa plant are toxic, except for the ripe fruit.

Interestingly, the Monstera deliciosa fruit takes nearly a year to ripen, and only when it is fully ripe can it be eaten safely.
