Soak mixed dals (lentils) for at least 5-8 hours or 2-3 hours in warm water. Rinse the soaked dals (lentils) thoroughly. Grind the dals (lentils) with garlic, ginger, ajwain, and green chillies without adding water, creating a coarse paste.
In a bowl, mix the dals (lentils) paste with finely chopped onion, coriander leaves, turmeric, coriander powder, hing (asafetida), salt, and besan (gram flour) and mix well.
Whisk the mixture for 2-3 minutes until light and fluffy.
Add a pinch of baking soda and a little water, then gently mix.
Heat oil in a pan.
Drop small portions of the mixture into the hot oil.
Fry on medium heat until golden brown and crisp.
Serve the hot bhaji (pakoda).
Optionally, you can add a bit of salt to the slit green chillies, fry them, and serve as a side.
