Where does this come from?

Have you ever been eating something and wondered where it comes from. Coming from a city family, I know alittle about gardening but certainly don't have a green thumb. In Cambodia, most of the food we eat is fresh from a garden and not from a grocery store. When this item in the picture showed up, I was totally curious. Of course, looking closely I recognized the shape at the bottom since I love to eat them. Cashews! They grow on trees and the Khmer like to eat the fruit besides the nut. I didn't care much for the fruit as it was pretty bitter. After a year, I am still seeing new vegetables. gail
