Kubili Nuts come from a tree, Cubilia blancoi, which grows mainly in the Philippines and also in the Moluccas and Sulawesi. The oval fruit is covered with spikes and about 5 cm (2") long. It contains a single, starchy nut resembling a chestnut, but with a less interesting flavour, although highly nutritious. The nuts have been sold in the Philippines under the name of castañas (chestnuts), and eaten boiled or roasted, but their future is uncertain; the tree has been classified as potentially needing protection.
