Vaati daal na khaman

In south guajarat we all love vati daal khaman,I never thought to make it my own, as it was easily available at each gulli, but here first time learned how to make it and its superb.. Felt the same smell of khaman at gulli's farsan shop :)Thanks to my neighbour aunty ..i was bit concerned about the oil part, but ok for once in 2 months or so ..or we can customize :)
Lets divide the whole recipe in four parts : soaking, grinding,steaming, tadka
(soaking)

Chana daal - 3 cups
Moong daal - 1/3 cup

(Grinding)
Ingredients:
Oil - 1 cup ( yeah it sounds too much )
Curd- 1 cup
gram flour- 2 tbsp
Method: grind the soaked ingredients with 1 cup oil and 1 cup curd. now keep one container in which we want to fermant , greece the container with the 2tbsp gram flour and oil (consistency should be very thin)
Add the grinded batter in the container , mix well
Let it ferment for 12 hours, thn keep in fridge for another 12 hour to 1 day

(Steaming)

Meanwhile add all the ingredients in batter, kept outside from fridge prior 1-2 hour of steaming. add the batter in the greased plate and let it steam for 25 mins

(Tadka)
Ingredients:
1 tbsp oil
mustard seeds, asofeteda
Coriander leaves, shreded coconut for garnishing
Method:
Here difference is , we have to let cool the steamed khaman and the tadka both..
Once both are cooled, add tadka, earlier i used to add hot tadka and mustard seeds remained stick sometime, but if we let it cool and spread with spoon, it will spread nicely
