As I told you, earlier also that dhokla is made and presented with lots of variation and this one is little bit spicy,looks like sandwich.
Mix fermented dhokla batter,along with other ingredients,and immediately transfer to greased plate and steam in pre steamed steamer for 20 min. (keep the dhokla's little bit thinner,then regular one)
Cool the dhokla,apply green chutney on it and cover with another,layer of dhokla,which is covered with tomato ketchup.press little bit,pour tempering on it,cut in square pieces and serve hot.
In a pan heat oil,and add all ingredients in given order,except,water,put off the heat and add water.
For Green Chutney:
In a grinder add all ingredients and churn till smooth paste,is obtained.
you can make sandwich dhokla with other dhokla batter too,but this one looks and taste really delicious.
