Yes, pakora batter can be made ahead of time, but it's best used within a few hours to maintain its leavening and prevent it from becoming too dense.
Making pakora batter ahead of time can save you valuable preparation time, especially when you're expecting guests or want a quick snack. The key is to understand how the ingredients interact over time. When you mix the dry ingredients (like gram flour, rice flour, and spices) with wet ingredients (like water or yogurt), gluten development begins. While gram flour has less gluten than wheat flour, some gluten development still occurs. Letting the batter rest allows the gluten to relax, which can result in a slightly smoother texture. However, if the batter sits for too long, the leavening agents (like baking soda or baking powder) will lose their effectiveness, and the batter can become dense and heavy.
Here's a step-by-step guide to making pakora batter ahead of time:
Add a pinch of baking soda or baking powder just before frying to give the pakoras a light and airy texture. Don't add it too early, as its leavening power diminishes over time.
