Notes
Many recipes say that you can make the jalebis instantly, but if you keep the batter for few minutes Jalebis come out very nice and crispy. If you want to make instantly add a 1 Tsp of Eno fruit salt instead of baking powder and add it after the batter is ready and you are ready to make Jalebi. But if you are making using baking powder, it is always better to keep the batter aside for a few minutes.
