Moth channa sprouts, also known as matki or moth bean sprouts, are the germinated form of moth beans (Vigna aconitifolia), which are a type of legume commonly grown in India, Southeast Asia, and other tropical regions. Sprouting is the process of soaking the seeds in water and allowing them to germinate and grow into young shoots, which are then consumed as a nutritious and flavorful ingredient in various culinary preparations.
