Sandwich Dhokla is yummy, easy to make, vegan & GF Gujarati snack which can be enjoyed for snacks or light meals.
Grind together coriander, mint, ginger, blanched spinach, sugar, salt, grated coconut and green chilies together using just a little bit of water. The chutney should be thick and smooth.
Add baking soda and salt to the idli batter. We divide it equally into 3 parts.
Add approximately 3 tbsp of the prepared chutney to one part of the batter. Leave the other two parts plain.
Prepare the steamer with enough water and place a stand in the steamer.
Grease a tin with oil. Pour 1 part of the plain batter. Spread it nicely and steam for 5-6 minutes.
Now, remove the tin from the steamer, layer the green chutney batter on top of the steamed white later. Now place the tin in the steamer and steam once again for 5-6 minutes.
Take the tin out the steamer once again, now layer the last part, the remaining plain batter. Spread it well. Place the tin back in the steamer, sprinkle some red chili powder, and some black pepper powder on top and this time let the dhokla steam for 12-14 minutes to allow all the layers to cook through.
Once the sandwich dhokla is steamed, take the tin out of the steamer. Allow it to cool for around 5-7 minutes. Then slice the dhoklas in any desired size and shape.
Heat the oil in a pan, once the oil is hot, add asafoetida, white sesame seeds, mustard seeds, and curry leaves. Let everything crackle and pop for about 2 minutes. Then pour this tadka (tempering) over the sliced sandwich dhokla.
Garnish the dhokla which some chopped coriander and along with different chutneys.
You can skip the green chutney and simply make plain white dhokla like idlis and give it a tadka.
