7. Let it cook for few minutes.
8. Flip it when done and cook for few seconds.
9. Flip again and apply 1 tbsp of red chutney on it. Sprinkle some chopped onions. 
10. Put 1 tbsp of potato masala/ stuffing in the centre. Fold the dosa.
11. Serve hot with coconut chutney and sambhar. 

PS:

•  I tried one with tomato chutney instead of red chutney.. The taste was quite good.
• If dosa batter is kept at 25 deg or higher temperature, then 12 hours would suffice for fermentation.
• If temp is less than 25 deg, then keep the batter for 24 hours for fermentation.
• For dosa batter, some people use only sona masoori rice with urad daal. They don't use idli rice. The ratio of sona masoori rice : urad daal is 2.25 cup (sona masoori rice): 1 cup (urad daal). Along this also add chana daal: 1 tbsp, fenugreek seeds: 1 tbsp. Rest everything is same as above.
