Kwai muk
Artocarpus hypargyreus · Moraceae · also known as Kwai muk, Kucap, Baji juniper fig (loosely)
A small, knobbly, orange-red relative of the jackfruit from southern China — soft, sweet-tart, and intensely flavored, with a sticky latex and an irregular shape. A rare backyard treasure, eaten fresh or dried into a chewy sweet.

The jackfruit family is famous for giants, but kwai muk is its charming miniature. Native to southern China, this small, knobbly, irregular fruit ripens to a soft orange-red and hides some of the most intense flavor in the whole genus — sweet-tart, aromatic, and faintly mango-like, packed into a fruit barely bigger than an apricot.
A backyard rarity
Kwai muk almost never reaches markets; it’s a dooryard tree of Guangdong, grown and shared by families who know its worth. Ripe fruit is eaten fresh the moment it softens, its reddish flesh sweet with a bright tang and a trace of the milky latex that runs through all Artocarpus fruits. Because it’s so perishable, the traditional way to keep it is to dry it into a chewy, concentrated sweet — a snack that carries its flavor through the year. Collectors have carried it to Florida and Hawaii as a curiosity, but it remains genuinely rare. Kin to the jackfruit, the marang, and the mulberry-family che, kwai muk proves that the smallest member of a family of giants can be the most concentrated of all.
