In a mixing bowl, add 2 cups jowar flour, ½ cup rava, and salt to taste. Mix well.
Add 3 cups water (or as required) and make a medium-thick, ribbon-like pouring consistency batter.
Cover and rest the batter for 10–15 minutes. Keep it aside.
Meanwhile, in a pan, add 1 tbsp oil, ½ tsp mustard seeds, 1 tsp cumin seeds, a pinch of hing, and 2–3 chopped green chillies. Sauté it.
Then add ½ cup chopped onion, ½ cup chopped capsicum, ½ cup chopped tomatoes, ¼ cup grated carrot, a pinch of salt, and 1 tsp red chilli flakes. Sauté on high flame for 2 minutes.
Switch off the gas and let the tempering cool down.
Now that the chilla batter is properly set, add the tempering to it. Mix well.
Then gradually add ½ cup water and make a thin, pouring consistency batter (refer to video).
Heat a pan on high flame and grease it with oil.
When the pan is super hot, lower the gas flame and pour the batter onto the pan.
Keep the flame on low-medium and cook the chilla until it turns crisp.
Now flip it over and roast until it turns golden brown and crisp.
Enjoy the jowar chilla with raw mango chutney or your favorite dip.
