Skipping the resting period for pakora batter results in pakoras that are less crispy and more likely to absorb excess oil. The resting time allows the gluten to relax and the batter to properly hydrate.
When you mix flour (typically gram flour, also known as besan) with water and spices to create pakora batter, gluten develops. Gluten is a protein that provides structure and elasticity. If you immediately fry the batter without resting, the gluten will be tense, leading to a tougher, less airy texture.
Resting the batter for at least 15-30 minutes allows the gluten to relax. This relaxation results in a more tender and crispy pakora. Furthermore, the resting period allows the flour particles to fully absorb the water, creating a more cohesive batter that coats the vegetables or other ingredients better. This improved coating helps prevent the pakoras from absorbing too much oil during frying.
Without resting, the batter might also be too thick or too thin, making it difficult to achieve the desired consistency for coating. The resting period gives you a chance to assess and adjust the batter's consistency before frying.
To ensure even crispier pakoras, add a tablespoon of hot oil to the batter after resting. This helps to create a lighter and more airy texture when frying.
