What can I do when dosa batter does not ferment overnight?
Check the actual temperature and batter history before extending fermentation. A warmer safe environment may help in cool weather, but do not leave batter indefinitely or ignore spoilage signs.
Why it happens
Dosa batter may not ferment overnight because the room is cool, the starting microbial population is weak, the batter is unsuitable in consistency, or the elapsed time is insufficient for the conditions.
How it works
Fermentation is driven by microbial growth and metabolism. Lower temperatures slow the process, while starting culture and ingredient composition affect how quickly acidity and gas develop.
