Yes, idli batter can be stored in ceramic bowls. Ceramic is non-reactive and doesn't affect the fermentation process or flavor of the batter.
Storing idli batter properly is crucial for successful fermentation and delicious idlis. Ceramic bowls are an excellent choice for this purpose due to several reasons:
Non-Reactive Material: Ceramic is generally non-reactive, meaning it won't interact chemically with the ingredients in the idli batter (rice and urad dal). This is important because reactive materials can alter the taste or inhibit fermentation.
Temperature Stability: Ceramic helps maintain a stable temperature, which is beneficial for consistent fermentation. Sudden temperature fluctuations can negatively impact the batter's rise.
Easy to Clean: Ceramic bowls are easy to clean and sanitize, ensuring no unwanted bacteria contaminate the batter.
Traditional Use: In many South Indian households, ceramic or earthenware pots have been traditionally used for fermenting idli and dosa batter.
However, ensure the ceramic bowl is food-grade and doesn't have any cracks or chips that could harbor bacteria. Also, leave enough space in the bowl for the batter to rise during fermentation.
Before storing the idli batter, lightly grease the ceramic bowl with oil. This prevents the batter from sticking to the sides and makes it easier to remove when you're ready to steam the idlis.
