In a mixing bowl, whisk together the gram flour, turmeric powder, and water until smooth.

Heat oil or ghee in a pan over medium heat. Add the cumin seeds, mustard seeds, and asafoetida and allow them to crackle for about 30 seconds.

Add the chopped onions, garlic, and green chili peppers and cook until the onions are soft and translucent about 5 minutes.

Pour the gram flour batter into the pan and stir well to combine. Cook the gram flour batter over low to medium heat and stir constantly to prevent lumps from forming.

Cook for about 5 minutes, stirring constantly until the mixture thickens and starts to pull away from the sides of the pan.

Remove from heat and stir in the lemon juice. (optional) Drizzle some mustard oil and achar masala.
