An authentic Indian specialty cooked with freshly ground roasted spices, caramelised onions, and aromatic herbs in the traditional style.
Drain the rice and dal, grind each to a smooth paste with minimal water, mix with the salt, and ferment overnight until frothy.
Splutter the mustard seeds in hot oil, sauté the onion and green chilies, add the turmeric and potatoes with a splash of water, and mash lightly.
Pour a ladle of batter on a hot greased tawa and spread it in a quick spiral into a thin circle.
Drizzle oil around the edges and cook until the underside is golden and lacy.
Place a spoon of potato masala in the centre and fold the dosa over.
Serve immediately with coconut chutney and sambar.
