1.After adding salt, always mix the batter well with hand as good bacteria in our hand helps in better fermentation.
2.To ferment in cold weather, cover and keep the batter inside grill oven. Turn on the oven light, close the oven and leave it for 8 to 10 hours. Do not turn on the oven ;)
3.If you have added more water while grinding, then the batter will be thin, and you can't make idlis. But don't worry, you can make dosas.
4.I usually add Red poha to increase the nutritional value. You can use white too. But do not skip poha as it helps in yielding soft idlis/dosas.
5.For babies below one year, do not add salt to batter. Click
