How Do Cashew Nuts Grow?

how do cashew nuts grow

Cashew nuts are a healthy, satisfying and completely natural snack. But where do they come from? Cashew nuts are the fruit of the cashew tree, an exotic tree now in many areas of the world but originating in Brazil, India and South East Asia – where the tree can grow and thrive in tropical climates.

Cashew growing begins with the cashew tree (Anacardium occidentale) which produces the cashew apple – attached to the branch, and the cashew seed – attached to the apple. The cashew apple is botanically recognised as an accessory fruit (or false fruit), which is different from real fruit in that it is not produced by the ovary of the plant. It is reddish or yellow in colour and around three times bigger than the cashew shells.

Locals harvest and use the cashew apple to make jams, curries and juice.

Whilst the cashew apple is edible and has a distinctly sweet flavour, it also has a fragile skin which makes it extremely perishable and so difficult to transport. So, the cashew industry mainly focuses on the seed of the tree, called cashew nuts.

Cashew nut shells are attached to the bottom of the cashew apple. Both of which form fully in the dry season. When it comes to harvesting cashew nuts, they are twisted and removed from the apples – usually by hand.

If they are super ripe, the nuts will detach themselves and fall to the ground.

The edible meat of the cashew is surrounded by a thick shell. Which is a potent source of a toxic and life-threatening compound called anacardic acid. Roasting cashews at a high temperature removes this compound. And allows the cashew shells to open, making the edible nut accessible. The final step is discarding those shells. And collecting the cream-coloured, kidney-shaped nuts we all recognise.

Who knew there was such an interesting story behind the super-easy cashew nuts so accessible to us today?
