Yes, multigrain idli batter can be portioned for weekly prep. Store the batter in airtight containers in the refrigerator for up to a week.
Multigrain idli batter, like regular idli batter, undergoes fermentation. This fermentation process continues even when refrigerated, albeit at a slower rate. Portioning the batter into individual containers minimizes the risk of contamination and allows for easy use throughout the week. Here's a step-by-step guide:
Prepare the Batter: Make your multigrain idli batter according to your preferred recipe. Ensure it has fermented properly.
Portion the Batter: Use a clean ladle or scoop to divide the batter into individual, airtight containers. Leave some headspace in each container, as the batter may expand slightly during refrigeration.
Refrigerate Immediately: Seal the containers tightly and place them in the refrigerator as soon as possible. Aim for a consistent temperature between 35-40°F (2-4°C).
Use as Needed: When you're ready to make idlis, take out one container at a time. Do not return unused batter to the refrigerator after it has been at room temperature.
To maintain the batter's consistency, stir it gently before using each portion. If the batter becomes too thick during refrigeration, add a tablespoon or two of water to achieve the desired consistency. Avoid over-stirring, as this can deflate the batter.
