Imagine if grapefruits turned greenish, shrank to the side of golf balls and lost their hard pith. That's the duku for you. Lansium Duranum, known in various languages as langsat, lansone, kokosan, gadu guda, lon bon and longkong duku grows throughout the tropical zones of Asia. They grow in clusters on trees, and are usually bought by the bunch. To eat a duku, cut it in half and simply squeeze until the fleshy lobes pop out of their jackets. It tastes remarkably like grapefruit, though some find it even more bitter (I don't). Duku are not widely available in the US (have any of you seen them?) but are ubiquitous in Malaysia, Indonesia, the Philippines and other parts of Southeast Asia.
