The traditional Tamil Nadu breakfast is never complete without idli sambar, dosa sambar, vada sambar or pongal sambar. A good lunch thali is never complete without sambar and rice with an assortment of vegetables, appalam (papad) pickle and curd (yogurt). Tea time or an evening snack of vada and sambar followed by piping hot filter kaapi can bring a smile on anyone’s face. Dosa and sambar or idli and sambar are again an evening ritual. The idli sambar combination has gone beyond the borders of Tamil Nadu and has become the breakfast of choice for millions of Indians. A suburban train ride in Mumbai in the morning will show how the idli sambar competes for share of the stomach of Mumbaikars along with vadapav.
