Transfer the fermented batter to a bowl and add water to the cleaner inner pot and turn on the “saute” mode to boil water.
While the water is heating, grease the idli molds with oil. Or if you are using paper cups, grease them with a thin layer of oil.
Add a small amount of batter in each mold and stack them in Instant Pot.
For paper cups: add ¾ cups of batter inside the paper cups then place the batter filled cups in a vessel and place the vessel inside the inner pot.
Close the lid and set the Instant Pot in “steam mode” in “venting” position. The timer function on the instant pot does not work in the venting position. So you have to use a separate timer.
In 5- 8 minutes, (10-12 minutes for paper cups), hot steaming Idlis will be ready.
Repeat steps 2 through 5 for the remaining batter.
Hot Steaming Idlis are ready to be served! Pair them with coconut chutney or sambar for a delectable experience.
