Small Onion Garlic Kulambu is a flavorful South Indian curry made with small onions (also known as shallots) and garlic, creating a rich, aromatic, and spicy dish. This kulambu (gravy) is often served as a side with rice, idli, dosa, or even roti. The small onions and garlic give the curry its unique taste, which is both savory and slightly sweet.
