B. motleyana, the most important of these, produces abundant clusters of fruit hanging in long strings. Each fruit is oval, about 4 cm (1") long, with a thin, velvety, pale brown skin. When ripe this skin becomes soft and wrinkled, which is one way of distinguishing rambai from the duku and langsat fruits which it closely resembles. A soft, translucent, whitish flesh surrounds a few flat, brown seeds. Cultivated varieties have a sweet, mild flavour and are refreshing when eaten raw. Wild trees produce fruits which are too acid to be eaten thus, but are suitable for cooking, making preserves, and alcoholic drinks. The sweet varieties are also used in these ways.
