The walnuts which seemed to exist about 5,500 years ago were found in Japan, which means that walnuts seem to be considered as valuable food together with chestnuts and Japanese horse chestnuts.
After the shell of walnut is cracked, there find two parts of walnut meats, which is called half size.
As the crispy taste of walnut increases a flavor, halves and pieces are used a lot as raw materials for confectioneries and breads.
As walnut is covered with shell, it happens that the piece of shell remains in shelled walnut meats.
