Do cashew nuts grow on trees?!

Yes, they do and here is the proof, a cashew nut fruit. 

Some cashew nut facts:

• India (home of the fruit above) is one of the largest cashew nut exporters. Vietnam is the largest exporter according to the latest Google results.
  
• Each fruit only bears one nut and it is on the outside of the fruit (the green bit at the top)

I thought cashew nuts "grew" in plastic bags at the supermarket. It is sad that we don't seem know or care how food is grown and where it is coming from. Next time before you put food in your mouth, ask yourself  - Where does it come from?
