Reusing pakora batter the next day is generally not recommended. The batter's consistency and flavor can change, and it may not rise as well, resulting in less crispy pakoras.
Pakora batter typically contains ingredients like gram flour (besan), spices, and sometimes a leavening agent like baking soda or baking powder. When left overnight, several things can happen that negatively impact the batter's quality:
Loss of Leavening Power: If the batter contains baking soda or baking powder, its leavening action diminishes over time. This means the pakoras won't be as light and airy.
Change in Consistency: The batter can become either too thick or too thin as the flour absorbs moisture or the ingredients separate. This affects how well it coats the vegetables and the final texture of the pakoras.
Flavor Alteration: The spices in the batter can become more pronounced or even develop a slightly off flavor after sitting overnight. This can change the overall taste of your pakoras.
Bacterial Growth: While less of a concern if refrigerated, there's still a risk of bacterial growth, especially if the batter contains ingredients like yogurt or other dairy products. This can compromise food safety.
For the best results, it's always preferable to make pakora batter fresh each time you plan to fry pakoras. This ensures optimal flavor, texture, and safety.
If you absolutely must save pakora batter, store it in an airtight container in the refrigerator and use it within 24 hours. Before using, check for any off smells or changes in consistency. You may need to adjust the batter by adding a little water or flour to achieve the desired consistency. However, be aware that the quality may still be compromised.
