Noticed your idli batter rising unevenly in the fridge? Learn the possible reasons, from temperature spots to the container you're using.
1 Answer
Refrigerated idli batter rises unevenly due to inconsistent temperature distribution and varying yeast activity within the batter. This results in some parts fermenting more than others.
Detailed Explanation:
Idli batter fermentation relies on the activity of naturally occurring yeasts and bacteria. When you refrigerate the batter, you slow down this fermentation process. However, the cooling isn't always uniform. The batter near the edges of the container might cool faster than the batter in the center. This temperature difference leads to varying rates of fermentation. The warmer parts of the batter will continue to ferment, producing more gas and causing those areas to rise more significantly. Additionally, the distribution of yeast and bacteria might not be perfectly homogenous throughout the batter. Some pockets might have a higher concentration of microorganisms, leading to localized areas of increased fermentation and uneven rising. Finally, repeated opening and closing of the refrigerator can cause temperature fluctuations, further contributing to inconsistent fermentation.
Pro Tip:
To promote more even rising, allow the refrigerated idli batter to sit at room temperature for a couple of hours before steaming. Gently mix the batter to redistribute the yeast and equalize the temperature before pouring it into the idli molds.
