Rata Kaju, commonly known as cashew nut, is a popular and highly valued nut in Sri Lanka. It is not only a delicious snack but also a key ingredient in many Sri Lankan dishes. Cashew nuts are derived from the cashew tree (Anacardium occidentale), which is native to Brazil but has been cultivated in Sri Lanka for centuries.
Cultivation of Rata Kaju in Sri Lanka
Cashew trees thrive in the dry zone of Sri Lanka, particularly in areas like Puttalam, Hambantota, and Moneragala. The tree is well-suited for arid climates and requires minimal maintenance. Cashew plantations are an important part of the local agricultural economy, providing employment to many farmers.
The cashew nut grows attached to the cashew apple, a fleshy, pear-shaped fruit. The nuts are harvested, dried, and processed before they are ready for consumption. Traditional methods of processing involve sun-drying and roasting the nuts to remove the toxic shell oil.
