Actually, there may be some misunderstanding of this sp. . This one is found in the wild and the nut wall is very very hard to
break and the nut contents are also very less in amount and difficult to retrieve from the nut wall compared to commercially
grown walnuts. Normally, we use a safety pin or any pointed object to retrieve the nuts. For your information, this is a very
essential dry fruit (a must) necessary during Bhai Tika ( Bhai Duj) in Nepali Hindu culture. Its nut bark is also very tometose
compared to the commercial variety. I think someone should study this sp. and find out the differences. I shall post you
the images of ready nuts if I can find them in the market !
