Lucuma (botanical name Pouteria lucuma) is a fruit native to the subtropical region and has its origin in the Andean region. Trees bearing this fruit are medium sized and grow up to a height of anything between 25 feet and 50 feet. Engravings of lucuma trees have been found on ceramics in the cemeteries of the native people in coastal Peru. In fact, the Moche people were fascinated with agriculture and usually desired to embody various vegetables and fruits, counting lucuma, in their art forms.
In 1531, the Europeans first noticed as well as reported lucuma in the Inca Empire's Chinchasuyu region. Occasionally, lucuma is also referred to as lucmo.

Precisely speaking, the term "eggfruit" actually denotes the dry flesh of the fruit, whose texture is similar to the yolk of a hard-boiled egg. The flesh of lucuma is especially dry and its flavor is somewhat unique - a blend of sweet potato and maple. Lucuma is highly nutritious and contains elevated levels of carotene, niacin (vitamin B3) and several other B vitamins. The fruit has a round or ovoid shape and its exterior is green. Inside, lucuma has a bright yellow flesh, which is usually fibrous in nature.

Lucuma trees usually grow at moderate elevations, anywhere between 1,000 meters and 2,400 meters in the coastal valleys of the Andes in Peru, Ecuador and Chile. Technically speaking, temperatures prevailing at this altitude in the native habitat of lucuma make this fruit tree subtropical. However, basically this tree is tropical in its native region. Lucuma has been successfully cultivated in California, especially in the subtropical mountain bases. However, endeavours to grow this fruit tree in Florida have failed owing to the climatic conditions prevailing there. Aside from Chile, Peru and Ecuador, lucuma is currently cultivated in Costa Rica and Bolivia. However, cultivation of this fruit tree in these regions is very limited. It has been found that lucuma thrives well in nearly all tropical regions, but is not generally favoured. Other species belonging to the same genus as lucuma are said to possess better flavours, for instance abiu (Pouteria caimito), mamey (Pouteria sapota), green sapote (Pouteria viridis) and canistel (Pouteria campechina). Large quantities of lucuma are also available in Asian countries like Vietnam and Laos.
Chemical analysis of lucuma has shown that this starchy fruit contains elevated levels of carotenoids, niacin (vitamin B3), in addition to high amounts of iron, calcium, sodium, phosphorus and magnesium.
Usually, lucuma fruits are harvested during the summer season - between January and April. Lucuma has a very short shelf life and the fresh fruits become rancid very quickly. Hence, people generally preserve this fruit by drying it out and subsequently pounding it into a fine powder form. Apart from helping to enhance the shelf life of lucuma, this method is also effective in retaining the flavor as well as the nutrients contained by the fruit. The process of dehydrating fresh lucuma fruits involves taking ripened fruits, washing them meticulously and then slicing them into small pieces. Subsequently, the fruit pieces are dehydrated by maintaining the temperature below 45°C with a view to save their nutritional substances. Once the fruits have dehydrated or dried out, the pieces are pounded into a fine powdered form and stored for use when needed. If you store lucuma in this method, the fruits will remain viable for about two years and its flavor as well as nutritional value will remain undamaged.
