Chok Loi

จอกลอย
Chok Loi · "Floating water lettuce (จอก is water lettuce, ลอย is floating). A folk gloss says the fruit is so light it would land on a leaf without sinking."
Also written: Chokloi · Chok-Loi · Jok Loi · Jawk Loi

A rare Chanthaburi heirloom traced to a single mother tree on the Punsri family farm, now grown in small numbers in Rayong and Nakhon Nayok and conserved in Nonthaburi. The standout trait is its tiny, personal-sized fruit, well under half a kilo. The eating profile is genuinely unsettled: one tasting read lightly sweet and caramel-floral with thin watery flesh, while Thai sources describe it as nutty and buttery, more rich than sweet, with coarser flesh. That likely reflects tree-to-tree variation in an unstandardized landrace, so we do not assert one taste. It is not commercially distributed and survives through heritage orchards and grafts, with no official registry record.
