Stir in turmeric powder, lemon juice, asafoetida powder, salt, and red chili powder. Set aside.

Add mustard seeds and cumin seeds. Allow them to crackle.

Add finely chopped onions, ginger, and garlic. Sauté until onions are soft and translucent.

Stir in the gram flour mixture to the onion mixture.

Turn the heat to low and keep stirring until the mixture leaves the sides of the pan and gets a shiny texture.

Turn off the heat and transfer the mixture to a greased rectangular pan.

Spread the mixture evenly.

Cut the mixture into square or diamond shapes once it cools.

Heat oil in a small pan.

Add sesame seeds and curry leaves and allow them to crackle.
