Edible Uses

Edible Parts: Oil Seed Edible Uses: Oil Seed - raw or cooked in soups, bread, biscuits, sweets etc[63, 101, 183]. The nuts have a thick shell with a small sweet kernel[183], they make an excellent dessert[K]. Although smaller than the seeds of cultivated species, the seed is of the same general quality[270]. Nuts at the 'milk' stage (before they are fully ripe) are softer and sweeter[183]. The seed is rich in oil. The seed ripens in mid to late autumn and will probably need to be protected from squirrels[K]. When kept in a cool place, and not shelled, the seed should store for at least 12 months[K]. An edible oil is obtained from the seed,
