COMMENT: Black walnuts differ from English walnuts because of their increased tannin content, which gives them a sharper taste. // Sap; Seed/Nut - raw or cooked. A sweet, rich distinctive delicious flavour it makes an excellent dessert nut and is also widely used in confections, cakes etc. The kernel is hard to extract and the oil it contains quickly turns rancid. The unripe fruits can be pickled. The seed is borne in solitary fruits or in pairs and is 3 - 4cm in diameter. The nuts can leave a permanent stain on clothing. An edible oil is obtained from the seed. A sweet taste but it tends to go rancid quickly. Used as a seasoning in bread, squash and other foods. The tree yields a sweet sap that can be drunk or concentrated into syrup or sugar. It is tapped in spring.(1)


Conventional advice on processing:

Editor:  It has been my limited experience that it is far less messy to let the walnuts dry thoroughly, with the hulls on, for several months before cracking open, avoids liquids staining hands and garments (although I haven't seen this advised anywhere).

 

CAUTION: The plant has occasionally been known to cause contact dermatitis in humans.(1)

 

NUTRITION/MEDICINAL:  A source of Omega 3 fatty acid. // Alterative;  Anodyne;  Antiinflammatory;  Astringent;  Blood purifier;  Detergent;  Laxative;  Pectoral; Vermifuge.(1)
