Now available: PLANTS FOR YOUR FOOD FOREST: an important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.

Edible Uses

Edible Parts: Fruit  Seed
Edible Uses:

Fruit - raw. Sweet and pulpy[1, 2, 46, 59, 61, 103, 173]. One report says that it is poisonous raw[153], though the writer might have been confused with the seed[K]. Seed - cooked[46, 59, 61, 128]. The seed needs to be soaked in salt water or thoroughly boiled or roasted in order to destroy a deleterious principle[1, 2, 63]. A staple food of the Maoris, it contains a tasteless farinaceous substance[2, 103]. The seed contains about 11% protein and 58% carbohydrate[173].

Pakeha (European,)plantings have proven the Karaka to be more frost tolerant than some believe, (Brian Molloy,Botany Division, DSIR, Lincoln (University, NZ) "The origin, relationships, and use of karaka or kopi." Maori have enjoyed eating the flesh of the berry for 1,000 years.)
