Santol (also known as cottonfruit) is native to the tropical regions of Southeast Asia. Santol fruit trees (botanical name Sandoricum koetjape) grow very rapidly and often reach a height of 150 feet. This tree produces ribbed leaves, while the flowers are yellowish-green or pink. The leaves measure about 1 cm in length.
It is believed that santol has its origin in erstwhile Indochina, particularly southern Laos and Cambodia, and Malaya. Perhaps this species was introduced to India, Indonesia, Malaysia, the Andaman Islands, Mauritius, the Moluccas and the Philippines long ago and over the years it has naturalized in these places. People in these tropical regions of Southeast Asia cultivate the plants widely and local markets sell copious amounts of these fruits.
In Malaysia and Asia, santol tree is not only held in esteem for its delicious fruit, but also for its timber. In addition, the santol tree is planted along the roadsides as a shade tree. These trees are also non-littering and wind-resistant.
Before we discuss the various aspects of santol fruit, it is worth noting that there are two different types of santol fruits - red and yellow varieties. Earlier, these two varieties of santol were believed to be two different species. However, the difference between the two varieties only exists in their colors. While the red variety of santol fruit is more common and the reddish leaves of the tree blended with the green leaves makes the trees more distinct as well as attractive. Usually, the shape, size and the somewhat fuzzy texture of santol fruits bear resemblance to those of peaches, but have an additional reddish shade. The skin of both varieties of santol fruits may either be thin and easy to peel or they may have a dense rind. To a large extent, this depends on the variety of the fruits. Usually, the santol fruits are edible and fruits of a number of cultivars may even enclose a milky juice.
The pulp located in the middle of santol fruit may have a sweet or sour flavour. The pulp contains small brown seeds, which are inedible. In a number of santol varieties, the external rind is relatively thicker and it comprises the actual edible part of the fruit. It tastes like a peach and to some extent has a combination of the flavour and texture of apples. In other varieties of santol, the external skin is relatively thinner as well as tougher. In such fruits, the whitish inner pulp enclosing the seeds is edible. In several cultivars, the inner pulp may have a somewhat sour flavour. As a result, such tree bearing such fruits is not as acceptable as those producing fruits with a thick rind. In fact, majority of the improve santol fruit varieties come with edible rinds that are extra thick. You can eat the rind of such fruits using a spoon after peeling off the outer most skin. Development of more such santol cultivars is likely to make the fruit more acceptable to people around the globe.
Harvesting of santol fruits is done manually. Harvesters generally climb the trees and pick the ripened fruits by hand. On the other hand, the ripened santol fruits can also be harvested by using a long stick with a forked end. The harvesters use the forked end of the stick to twist off the fruits from the trees. Generally, people eat the santol fruit pulp by itself or after adding spices to it. Some people also cook the pulp or use it for making candies or marmalades.
