Gently fold the salt into the batter. Do not mix vigorously as you break down the bubbles.
Bring two cups of water to a rolling boil in the pressure cooker.
Pour the batter into the idli moulds and place moulds into the pressure cooker. Seal pressure cooker and cook on low heat for 12 minutes.
When cooked, release pressure quickly and remove idli from the moulds. They should not stick because of the steaming process. Serve immediately.
notes
If you do not have idli batter to hand, this recipe must be started the day before with the preparation of the batter. Our recipe for idli batter is straightforward, but needs an overnight fermentation period.If you do not have idli moulds, small ramekins would be suitable, provided you grease them lightly.
