Kadamba sambar is a traditional flavorful South Indian curry prepared with assorted (kadambam) vegetables & tubers usually served with rice. It is popularly known as idi sambar (meaning pounded sambar) in Tirunelveli & Kanyakumari regions, as the spice powder was earlier prepared by pounding in a large stone mortar (ural) using a 3-feet long metal-tipped wooden pestle (ulakkai).
