To make authentic idlis, one needs the idli maker and an idli stand. This idli stand has four round tiers, 10 inches in diameter. Each tier has four concave depressions where the idli batter is poured. The trays are stacked and secured through a center rod, then placed in its covered pot with just enough boiling water to keep the bottom tray dry. Directions To Use : – Grease the idli moulds and spoon the batter into them. – Heat water in the idli cooker. Steam cook for about 12-15 mins on high. – Take out from the fire and let cool for a while and then remove the idlis from the molds.
