Walnuts

The walnut is native to SE Europe and West & Central Asia but is now grown in the UK, California and China as well. It is grown for timber as well as its nuts. Walnut oil has been used for centuries in the preparation of artists paints. The black walnut is a native of North America, introduced into Britain in the 17th century. The butternut is also from North America. These two have much thicker shells than European walnuts. High in fat, they go rancid very quickly and should be stored in the fridge or freezer. 100g walnuts contain 10.6g protein and 2.4mg iron.
