Edible Uses

Edible Parts: Sap Seed Edible Uses: Seed - raw or cooked[61, 101, 161]. Very variable in quality, some are sweet and pleasant whilst others are bitter and astringent[1, 2, 11, 46, 63, 183]. In general it is inferior to other hickories[117, 159]. The nut is rather small[K], has a very thick shell and contains very little edible matter[82, 226]. The seed ripens in late autumn and, when stored in its shell in a cool place, will keep for at least 6 months[K]. Sap - tapped in spring and used as a refreshing drink. Sweet[101].
