Idli is traditional South Indian steamed cakes made from a naturally fermented batter of hulled black lentils (urad dal) and rice. Light, pillowy, and mildly flavored, they are a healthy, vegan, and gluten-free staple. They are universally served piping hot alongside sambar (a savory, spicy vegetable & lentil stew), fresh coconut chutney & tomato chutney.
