The cooking time would really depend on your Microwave and the quantity you are making. I used a 4 year old Samsung combi MW and made a small batch, as I was cooking only for myself that day. I am only recapping Sia's recipe, see her post for the detailed version.
1/3 cup besan
1 cup buttermilk ( 1/3 dahi+ 2/3 water)
Add salt, turmeric, chili powder, hing
Mix well. MW on high for 11 minutes stirring every 3 minutes. Spread on greased thalis. cool, cut, roll, temper, eat.
This is where I deviated a bit from the recipe, and used the tadka that my mom does for khandvi, which needs:
1 tsp oil, 1/4 tsp mustard, 1/2 tsp sesame seeds, 2 curry leaves and a pinch of red chilli powder.
Heat the oil in a tadka pan, add sesame and mustard seeds, and curry leaves (watch out for the splutter!). Take it off the heat, wait for 5 seconds and add the red chilli powder. Spoon on the khandvis.
MW Khandvi goes to T&T: Monsoon Spice hosted by Zlamushka. Thank you Sia, for a lovely and lazy khandvi recipe.
