In a bowl, add maida, corn flour, ginger garlic paste, turmeric powder, pepper powder, garam masala powder, coriander powder, cumin powder, Kashmiri chilli powder, chilli powder, lemon juice, yogurt, and salt. Mix them well.
Gradually add water to make a smooth batter without any lumps. The batter should be neither too thin or too thick.
Add paneer cubes to the batter and coat the paneer cubes well on all sides. Do this gently without breaking the paneer.
Let it sit for at least 15 minutes to absorb flavours.
Heat oil in a pan and deep fry the paneer pieces until golden brown. Remove excess oil by placing the fried paneer on paper towels.
In the same oil, fry the curry leaves and add them to the paneer 65.
Plate the crispy paneer with onion rings and lemon wedges for garnish. Serve with some mint coriander chutney or tomato ketchup on the side.
Notes
Adjust spices to suit your taste. Make sure all paneer cubes are well coated in the batter. You can refrigerate the marinated paneer and let it absorb the flavours for a while.
