An authentic Indian specialty cooked with freshly ground roasted spices, caramelised onions, and aromatic herbs in the traditional style.
Soak the rice and urad dal with fenugreek separately for 4 hours.
Grind together into a smooth batter, mix in the salt, and ferment overnight.
Heat 1 tbsp oil, pop the mustard seeds and curry leaves, then add the turmeric and mashed potatoes with a splash of water; cook into a dry masala.
Spread the batter thin on a hot greased griddle and drizzle oil around the edges until crisp and golden.
Place a spoonful of potato masala in the centre, fold the dosa over, and serve hot with chutney and sambar.
