Longkong fruits are ovoid, roundish orbs around five centimeters in diameter, usually found in clusters of two to thirty fruits. Each round fruit is covered by yellowish, thick, leathery skin. Underneath the skin, the fruit is divided into five or six slices of translucent, juicy flesh.
The flesh is slightly acidic in taste, although ripe specimens are sweeter. Green seeds are present in abound half of the segments, usually taking up a small portion of the segment although some seeds take up the entire segment’s volume. In contrast with the sweet-sour flavor of the fruit’s flesh, the seeds are extremely bitter.
The sweet juicy flesh contains sucrose, fructose, and glucose.
The peak season is from May to September.
