Bhaji batter should be thick enough to coat the vegetables evenly without being too runny. A good consistency is similar to pancake batter.
The ideal consistency of bhaji batter is crucial for achieving crispy and delicious bhajis. If the batter is too thin, it will slide off the vegetables during frying, resulting in uneven coating and greasy bhajis. On the other hand, if the batter is too thick, it will create a heavy, doughy coating that doesn't cook through properly and can be unappetizing.
To achieve the perfect consistency, start by mixing your dry ingredients (such as gram flour, rice flour, spices, and salt) in a bowl. Gradually add water, mixing continuously, until you reach a smooth batter that coats the back of a spoon and slowly drips off. You should be able to dip a vegetable into the batter, and it should cling to it without running off immediately. If the batter is too thick, add a little more water, one tablespoon at a time, until you reach the desired consistency. If it's too thin, add a little more gram flour, one tablespoon at a time.
The type of vegetable you are using can also influence the ideal batter consistency. For vegetables with a higher water content, like onions or potatoes, you might want a slightly thicker batter to ensure it adheres properly.
Let the bhaji batter rest for about 15-20 minutes before frying. This allows the gluten in the gram flour to relax, resulting in a lighter and crispier bhaji.
