Peerkangai gothsu has been my favorite since my school days. My granny used to make this with loads of gingely oil for idlis. This is her signature dish.
We often have idli batter, but keep thinking as of what to prepare other than the usual sambhar and chutney varieties. This is a great alternative for it. This is famous among the people of Mannarkudi, a town in Thiruvarur district of Tamilnadu and the people of Chidambaram.
