How are Idlis made? Can you find out how idlis are made? Is there something that makes the idli batter fluffy? Do you know what it is?
Idlis are made by soaking rice and urad dal (black gram), grinding them into a batter, and fermenting the batter overnight.
During fermentation, microbes from the air help make the idli batter rise and become fluffy. These microbes produce gas bubbles that make the batter light and soft.
The fermented batter is then steamed in idli moulds to make soft, fluffy idlis.
Explanation
Finding #7 in the chapter states that microbes in the air help make idli batter rise. This is an example of how some microbes are helpful—they cause fermentation which makes the batter fluffy and gives idlis their soft texture.
