Add 1 tsp sugar, 1 tsp salt, ¼ tsp turmeric, ¼ tsp hing, ½ cup water, and whisk everything well.
Use water in batches to set the consistency of the batter.
After perfect consistency is formed, cover and let it rest for 10 minutes.
Meanwhile, grease the mould nicely and keep it aside.
Take a mixer jar, add 1 cup corn, 1 inch ginger, 2 green chilli, and blend well to form a paste.
After 10 minutes, add the blended mixture to the batter with 1 tbsp oil and mix well.
Add 1 pack ENO, 1 tbsp water to activate it, and gently mix.
Transfer it to the greased mould and tap to remove the bubbles.
Heat water in a pan and set the stand in it. Place the mould on it.
