Classic Idli is a popular South Indian breakfast dish made with fermented rice and lentil batter. It is a steamed cake-like dish that is soft, fluffy, and light. The batter is made by soaking rice and lentils, grinding them into a smooth paste, and fermenting it overnight. The fermented batter is then poured into idli molds and steamed until cooked. Serve hot with coconut chutney and sambar for a delicious and healthy breakfast.
