The Mystery of the Prehistoric Devil Nut
At first glance, it looks like a creature from a fantasy film—a dark, hard shell equipped with sharp, sinister-looking horns. Many mistake it for a decorative carving or even a fossil. However, this bizarre object is actually an edible aquatic fruit known by several intriguing names, such as the buffalo nut, bat nut, or devil’s nut. Belonging to the Trapa genus, these peculiar freshwater fruits hide a surprising culinary secret beneath their intimidating exterior.
Beyond its strange appearance lies a crisp, starchy kernel with a mild, nutty flavor remarkably similar to a chestnut. Popular in traditional dishes across South Asia—where it is widely known as singhara—it is often boiled, steamed, or ground into flour for sweets and stir-fries.
Despite its long culinary history, consuming this unusual fruit comes with important precautions. It is entirely different from the common Chinese water chestnut, which grows underground as a corm rather than floating in lakes. Furthermore, because it thrives in freshwater environments, eating it raw carries severe health risks from aquatic parasites. Thorough boiling is essential, and one must take extra care when cracking the shell, as those sharp outer horns can easily cause injury before you reach the edible center.
