South Indian cuisine 
is distinguished by a greater emphasis on rice as the staple grain, the liberal use of coconut and particularly coconut oil and curry leaves, and the ubiquity of sambar and rasam (also called saaru'/'chaaru) at meals.
The dosa, idli, vada, bonda, and bajji are typical South Indian snacks(These are generally consumed mainly as breakfast) . Andhra, Chettinad, Hyderabadi, Mangalorean, and Kerala cuisines each have distinct tastes and methods of cooking. In fact each of the South Indian states has a different way of preparing sambar; a connoisseur of South Indian food will very easily tell the difference between sambar from Kerala and sambar from Tamilnadu and pappu pulusu in Andhra cuisine.
