Why do we never buy cashew nuts with shells?

Have you noticed a "strange phenomenon", even nuts with shells so thick that they can break their teeth, such as walnuts, hazelnuts, and macadamia nuts, will have shelled versions in **. However, there is one nut that we have never seen in the supermarket in its shell version, and that is cashews.

Think about it carefully, do all cashew nuts on the market look like this?

Why is it such a popular cashew nut, but I have never seen it sold in the shell, Xiaoqia will help you answer!

The lower half of the kidney-shaped seeds are the cashew nuts we are familiar with, and its shell contains extremely corrosive "cashew nut shell oil", and even greedy animals have to discard the nuts after tasting them. Thus, cashew nuts both fulfill the task of spreading the seeds and protecting the seeds from being eaten, which is impressive.

It is also because the cashew nut shell contains "cashew nut shell oil", which needs to be manually shelled.
