Classic Uttapam is a popular South Indian dish made with fermented rice and lentil batter. It is a thick pancake-like dish that is typically topped with finely chopped onions, tomatoes, green chilies, and coriander leaves. The batter is made by soaking rice and lentils overnight, grinding them into a smooth paste, and allowing it to ferment for a few hours. The fermented batter is then spread on a hot griddle and cooked until golden brown. Classic Uttapam is usually served with coconut chutney and sambar, a lentil-based vegetable stew.
