In a mixing bowl, add ½ cup curd, ¼ tsp turmeric powder, 1 tsp red chilli powder, 1 tsp coriander powder, salt to taste, ½ tsp garam masala, a pinch of hing, and ½ tsp ajwain. Mix well.
Add 1.5 cups bajra flour and ½ cup besan. Gradually add 1.5 cups water and prepare a medium-thick, ribbon-like pouring consistency batter. Whisk the batter for 2 minutes, then cover and rest for 10 minutes.
In a tadka pan, heat 2 tbsp oil. Add 1 tsp cumin seeds, ½ tsp mustard seeds, 1 tbsp white sesame seeds, a few curry leaves, 3 chopped green chillies, and 1 tbsp ginger-garlic paste. Sauté briefly.
Add this tadka into the batter along with ½ cup chopped onion and ½ cup chopped coriander leaves. Mix well.
Heat a pan on high flame, grease with oil, and sprinkle some sesame seeds.
Once the pan is hot, lower the flame and pour the batter onto the pan.
Cook on medium-low flame until the pudla turns crisp.
Flip and roast the other side until golden brown and crisp.
Serve hot bajra pudla with garlic chutney.
