How long can uncooked dosa batter be kept in fridge?

Question

What is the shelf life of uncooked dosa batter in the fridge? Learn how long it typically lasts and the signs that it has over-fermented.

Answer 1

Uncooked dosa batter can typically be stored in the refrigerator for 3-5 days. After this period, the fermentation process can become too active, affecting the taste and texture of the dosas.

Detailed Explanation:

Dosa batter is a fermented mixture of rice and lentils. The fermentation process continues even when refrigerated, albeit at a slower rate. Storing the batter in the fridge helps to slow down the fermentation, preventing it from becoming overly sour.

Here's a breakdown of the storage timeline:

1. Day 1-3: The batter is usually at its prime for making dosas. The fermentation is active enough to give the dosas a light and airy texture.
2. Day 4-5: The batter may become slightly more sour, but it's still generally acceptable for use. You might notice a stronger fermented smell.
3. Beyond Day 5: The batter can become excessively sour and may develop an unpleasant taste. The dosas might also become too soft or sticky. It's generally best to discard the batter at this point.

It's important to store the batter in an airtight container to prevent it from absorbing odors from the refrigerator and to minimize further fermentation.

Pro Tip:

To extend the shelf life of your dosa batter, you can freeze it. Divide the batter into smaller portions and freeze them in airtight containers or freezer bags. Frozen dosa batter can last for up to a month. Thaw it in the refrigerator overnight before using.
