Prep time: 10 min
Cook time: 20 min

A light, fermented rice gruel traditionally used for rehydration and gentle digestive support.

Kanji is a traditional, light, and easily digestible fermented rice gruel that serves as a cornerstone of Ayurvedic digestive recovery. By fermenting the rice water, the preparation gains a subtle sourness (Amla) that stimulates Agni (digestive fire) while remaining gentle on the gastrointestinal tract. It is highly valued for its rehydrating properties, particularly during the hot summer months (Grishma) or the humid, damp transition of the monsoon (Varsha). In the Ayurvedic tradition, this preparation is often used as a 'peya' or 'vilepi'—a thin, nourishing gruel—to support the body during convalescence or following cleansing therapies. The fermentation process enhances the bioavailability of the rice, making it a soothing, cooling, and restorative meal that pacifies Vata and Pitta doshas without overwhelming the digestive system.
