Make & Ferment the Batter: In a medium bowl, combine the sifted chickpea flour, green chilies, ginger, black pepper, turmeric, salt, asafetida, and sugar.
Stir in the 3 tbsp (45 ml) melted ghee/oil and yogurt/buttermilk to form a thick batter.
Cover and let it rest in a warm place for 8 hours or overnight to ferment.
Prepare for Steaming: Set up your steamer with about 1. 25 inches / 3. 5 cm of water, ensuring your 8-inch round or square cake pan will sit above the water.
Bring the water to a boil over moderately high heat. Thoroughly grease the cake pan with 1 tbsp (15 ml) of melted ghee or oil.
Activate the Batter: Just before steaming, add the baking powder and baking soda to the fermented batter.
Pour in the 3 tbsp (45 ml) of warm water and stir gently in one direction just until the batter becomes light and frothy.
Do not overmix.
Steam the Dhokla: Immediately pour the frothy batter into your greased pan.
Place the pan in the steamer. Lay a clean tea towel across the top of the pot before placing the lid on firmly; this prevents condensation from making the dhokla soggy. Steam for 8 to 12 minutes.
Check for Doneness: Insert a toothpick into the center of the dhokla. If it comes out clean, it's done. Carefully remove the pan from the steamer and let it rest, loosely covered, for 10 minutes.
Cut & Garnish: Invert the dhokla onto a cutting board and cut it into 1. 5-inch diamond or square pieces.
Arrange them on a serving platter and sprinkle with the grated fresh coconut and chopped coriander.
Prepare the Tempering (Chaunk): Heat 0. 25 cup (6000 ml) ghee or butter in a small pot over moderate heat.
Once hot, add the black mustard seeds and wait for them to pop. This happens very quickly! Immediately and carefully pour the hot tempering evenly over the dhokla pieces.
Serve: Enjoy your delicious homemade dhokla warm or at room temperature.
After adding baking soda and water, stir the batter in one direction only and work quickly to get it into the steamer. This traps the air bubbles for a spongy texture.
Don't skip the fermentation.
Resting the batter overnight develops the classic tangy flavor and aids in a softer texture.
