You will also need a steamer with idli plate rack.
Once the batter is well fermented, very slowly fold the batter to combine. By mixing slowly you will retain the fluffiness of the batter that will help the idli's remain soft and fluffy even after steaming.
Prepare the steamer with a little water in the bottom.
Grease the idli molds with a little oil and pour spoonfuls of the batter into these moulds. Place inside the steamer and steam for 10 to 12 minutes.
Once steamed, remove from the steamer and allow it to rest for 2 to 3 minutes before you can remove the idli's.
Tip: For removing the idli's fill a small bowl filled with water. Dip a spoon in the water and then scoup the idli's out starting from the edges. Dipping the spoon in water helps in the easy removal of idli's from the plates.
