Home cooks struggle to achieve consistent fermentation results when making traditional dosa batter

Home cooks attempting to make dosa from scratch face unpredictable fermentation outcomes due to lack of understanding about the biological processes involved. Without clear guidance on fermentation timing, temperature control, and microbial activity, batches often fail to rise properly or develop the desired tangy flavor, forcing people to either abandon homemade dosa or repeatedly waste ingredients through trial-and-error.
