As far as I know, idli is one of the safest foods the south Indians consume regularly. If you know the preparation method, it is a quick and easy food.
Masala Idli prepared at home using ID Batter
In a large family, the idly batter is prepared and allowed to ferment overnight. In the morning, Idly is prepared in a large vessel (specially made to prepare idly) and served to the members of the family. More than 20 idli’s can be prepared on one go (depends on the size of the vessel).
