An authentic Indian specialty cooked with freshly ground roasted spices, caramelised onions, and aromatic herbs in the traditional style.
Soak the rice and the urad dal with fenugreek seeds separately for 4 hours.
Grind both to a smooth batter and ferment overnight until risen.
Stir the salt into the batter.
Temper the mustard seeds, green chilies, and onion, then mix with the mashed potato and turmeric.
Ladle the batter onto a hot tawa and spread it into a thin circle.
Drizzle with oil and cook until crisp and golden, then add the potato filling.
Fold the dosa over the filling and serve with chutney and sambar.
