Edible Uses

Edible Parts: Fruit Edible Uses: Fruit - raw or cooked. The fruit is usually bletted if it is going to be eaten raw[1, 2, 3, 11, 115, 183]. This involves storing the fruit in a cool, dry place until it is almost but not quite going rotten. At this stage, the fruit tastes deliciously like a luscious tropical fruit[K]. The fruit will often begin its bletting process whilst still on the tree, and we have eaten delicious fruits straight from the tree in mid-September[K]. The fruit can also be dried and used like prunes. The fruit is up to 3cm across[200].

Known Hazards

The seeds probably contain hydrogen cyanide. This is the ingredient that gives almonds their characteristic flavour. Unless the seed is very bitter it should be perfectly safe in reasonable quantities. In small quantities, hydrogen cyanide has been shown to stimulate respiration and improve digestion, it is also claimed to be of benefit in the treatment of cancer. In excess, however, it can cause respiratory failure and even death.
