Why does my idli turn dense or hard?
Look at fermentation, batter texture and steaming conditions together rather than blaming one factor. Use a consistent method and avoid rough handling after the batter has developed gas.
Why it happens
Idlis become dense when the batter has insufficient aeration, the fermentation is weak, the grind or consistency is unsuitable, or the batter is handled in a way that removes bubbles. Steaming conditions also affect expansion and setting.
How it works
Gas bubbles expand during steaming, while starch and proteins set around them. If there are too few bubbles or the structure sets poorly, the idli becomes compact rather than airy.
