Wampee or wampi is a small evergreen tree that grows naturally in northern Vietnam, southern China, and Laos. The fruits are round to oblong and grow in clusters. The flesh is juicy and grape-like, with sweet to subacid flavors. Fully ripe fruits are usually eaten fresh out of hand or used in fruit salads and various desserts.
They’re considered a delicacy in Vietnam, where they’re made into jams, jellies, and beverages, and in China, where pieces of wampee are an ingredient in savory dishes based on chicken and meat. There are several common varieties of the wampee, such as Chi Hsin, with a sweet flavor, and Guy Sam, well-known for its tangy and sweet aroma.
