In a mixing bowl, add 1 cup jowar flour, ½ cup rava, and salt to taste. Mix well.
Add 2 cups buttermilk, or as required, and make a thick, ribbon-like pouring consistency batter. Do not make the batter thin.
Cover and rest the batter for 10–15 minutes.
Now, grate small pieces of dudhi (bottle gourd) using a large-hole grater. You will need 1 cup of grated dudhi.
Add 1 tbsp ginger-green chilli paste, 1 cup grated dudhi, a pinch of salt, a pinch of hing, 1 tbsp sugar, and 2 tbsp oil to the batter. Mix well.
Finally, add 1 tsp Eno fruit salt and a little water to the batter. Mix gently and immediately proceed with steaming.
