Idli Rasam is a popular South Indian combination where soft and fluffy idlis are served with tangy and spicy rasam. Idlis are steamed rice and lentil cakes, while rasam is a thin and flavorful soup made with tamarind, tomatoes, spices, and herbs. The idlis are typically soaked in the hot rasam, allowing them to absorb the tangy and aromatic flavors. The combination of the light and fluffy idlis with the spicy and tangy rasam creates a comforting and satisfying meal. Idli Rasam is commonly enjoyed for breakfast or as a light lunch or dinner option.
