If you are making your batch of idlis fresh then refrigerate it at least for 30mins.
Then cut the idlis into small cubes. In a mixing bowl mix all the ingredients under ‘for the batter(except oil and idlis)’ add little water to form a thick paste.
Dip the idlis cubes into the batter and tawa toast it(or deep fry).
I used my trusted Nirlep tawa, added less oil and toasted till golden brown. Drain in tissue paper.
