Why do my idlis sometimes stick to the molds, even when they are greased?

Question

Why do your idlis sometimes stick to the molds? Find out the common reasons, even when the molds are properly greased.

Answer 1

Idlis stick to the molds due to insufficient steaming, uneven batter consistency, or inadequate greasing. Ensuring proper steaming time, a well-fermented batter, and thorough greasing are key to preventing sticking.

Detailed Explanation:

Several factors can contribute to idlis sticking to the molds, even when greased. Let's break them down:

1. Insufficient Steaming: The most common reason is under-steaming. Idlis need sufficient steam to cook through and release easily. If they are removed too early, they will stick. Ensure the idlis are cooked until a toothpick inserted into the center comes out clean. This usually takes around 10-12 minutes, but can vary depending on your steamer.
2. Uneven Batter Consistency: A batter that is too thick or too thin can cause sticking. A thick batter may not cook evenly, while a thin batter may not hold its shape and stick to the mold. The ideal batter consistency should be similar to that of a thick milkshake.
3. Inadequate Greasing: While you are greasing the molds, the type of grease and how thoroughly you apply it matters. Use a neutral oil like vegetable oil or ghee. Ensure every nook and cranny of the mold is coated evenly. A thin layer is usually sufficient; too much can also cause issues.
4. Poor Fermentation: Proper fermentation is crucial for light and fluffy idlis. If the batter hasn't fermented adequately, the idlis will be dense and more likely to stick. Fermentation time varies depending on the weather; warmer climates require less time.
5. Mold Material: The material of your idli molds can also play a role. Stainless steel molds are generally less prone to sticking than aluminum molds, especially if the aluminum is not well-seasoned.

Pro Tip:

After steaming, let the idlis cool slightly in the steamer for a minute or two before removing them. This allows them to firm up a bit, making them easier to release from the molds. Use a spoon or a thin spatula to gently loosen the edges before lifting them out.
