Water caltrop is a unique aquatic plant that grows in ponds, lakes, and slow-moving water. Known for its dark, hard shell and white, starchy interior, this traditional food has been consumed in many Asian countries for centuries. While it may look unusual, water caltrop is valued not only for its taste but also for its nutritional benefits.
