•	1/2 teaspoon fenugreek seeds
•	Salt, to taste

Ingredients for Potato Filling:
•	4-5 medium potatoes, boiled, peeled, and mashed
•	1 onion, finely chopped

Instructions:
o	Wash and soak urad dal, rice, poha, and fenugreek seeds separately in water for 4-6 hours or overnight.
o	Grind the soaked dal and fenugreek seeds together to a smooth batter. Grind rice and poha together to a slightly grainy texture. Mix both batters, add salt, and mix well. Ferment overnight or until batter rises and is slightly bubbly.
o	Heat oil in a pan. Add mustard seeds and let them splutter.
o	Add cumin seeds, asafoetida, and curry leaves. Sauté for a few seconds.
o	Add chopped onions and green chilies. Sauté until onions turn translucent.
o	Add turmeric powder and mashed potatoes. Mix well and cook for 2-3 minutes. Adjust salt to taste. Set aside.
o	Heat a non-stick or cast-iron skillet over medium-high heat. Grease lightly with oil.
o	Pour a ladleful of dosa batter onto the skillet and spread it in a circular motion to form a thin crepe.
o	Drizzle oil around the edges. Cook until the bottom turns golden brown and crisp.
o	Spread a spoonful of potato filling over one half of the dosa. Fold the dosa over the filling.
o	Serve hot with coconut chutney and sambar.
