In a mixer jar, add besan, salt, sugar, turmeric powder, hing, chopped green chili, lemon juice, and water. Grind it into a smooth paste.
Transfer the ground batter into a mixing bowl and add oil to it. Mix well and whisk the batter for 2 minutes.
Cover the batter and let it rest for 10 minutes.
Now, add 1 packet of lemon-flavored Eno to the batter and mix well.
Pour the batter into a greased steel plate.
In a cooker, add 3-4 cups of water and place a stand in the center. Preheat the cooker for 5 minutes.
Place the dhokla plate on the stand in the cooker. Cover the cooker with a lid, without the whistle, and steam the dhokla on medium-high flame for 15 minutes.
Once the dhokla is properly steamed, allow it to cool down slightly.
Cut the dhokla into square pieces.
In a tadka pan, add oil, mustard seeds, slit green chilies, and curry leaves. Sauté them.
Add 1/4 cup of water and sugar to the tadka. Stir continuously until the sugar is completely dissolved.
Pour the tadka mixture over the dhokla pieces. Mix well.
Garnish with coriander leaves and serve with chutney.
