Legend has it these grubs were once sent to the Nguyễn royal court as a tribute delicacy prized enough for an emperor's table — though, like much of the Mekong Delta's food lore, the story is passed down rather than documented.
The plump, cream-colored larvae of the coconut palm weevil are pulled live from the trunks of dying coconut trees, then grilled, deep-fried, or eaten still wriggling in fish sauce. Mekong Delta markets, especially around Bến Tre's coconut groves, sell them as a prized, faintly sweet delicacy rather than a novelty.
