During summer months, the poor rise in urad dal batter can be attributed to several factors: Factors Affecting Fermentation 1. High Temperatures: Summer temperatures can be too high for the natural yeast and bacteria present in the batter to ferment properly. Ideal fermentation temperature is between 25°C to 30°C (77°F to 86°F). 2. Low Humidity: Dry air during summer can slow down the fermentation process, leading to a poor rise. 3. Increased Water Evaporation: Higher temperatures cause water to evaporate faster, leading to a thicker batter that's harder for the microorganisms to ferment. 4. Reduced Microbial Activity: High temperatures can kill or inhibit the growth of beneficial microorganisms, such as lactic acid bacteria and yeast, which are essential for fermentation. 5. Over-Fermentation: In some cases, the high temperatures can cause the batter to over-ferment, leading to a sour taste and a poor rise. Tips to Overcome Summer Fermentation Issues 1. Use a cooler place: Stor...
