Did you know that cashews grow on trees?
Here is the tree:
You can reap the fruit when it is yellow:
The little brown seed under the fruit contains the cashew. The seed needs to be cooked first; after the cooking you get the cashew as we know it.
You can even eat the yellow fruit - but since only our guide ate it I have no idea how it tastes. Often malagasy people would tell me: I can eat it, but I dont know if your stomach will make it ...
To be honest: I dont try when someone tells me that.
