Makhana are the popped, edible seeds of the prickly water lily Euryale ferox, eaten across the Indian subcontinent as a fasting-friendly snack, dessert ingredient, and curry thickener. Despite being often classified as a nut, they are starch-rich, gluten-free seeds with a light, puffed texture when roasted.
History & Origins
Cultivation of Euryale ferox in the wetlands of Bihar dates back at least to the Mauryan period (c. 3rd century BCE), with the plant referenced in classical Ayurvedic and Buddhist texts as a strengthening food for ascetics. It was introduced to Chinese pond cultivation during the Han dynasty and remains a traditional Lunar New Year ingredient in eastern China. In modern India, Darbhanga and Purnia districts remain the global hub for makhana processing, accounting for the majority of world production.
