Rinse & soak: Rinse idli rice and urad dal separately until water runs mostly clear. Soak in enough water to cover by 2–3 cm for at least 2 hours, or until plump.
Grind: Drain most of the soaking water (reserve some). Blend using small amounts of water until smooth and thick, slightly thicker than pancake batter.
Ferment: Transfer batter to a large bowl and add salt, cover loosely, and ferment overnight or at least 8 hours until bubbly and nearly doubled in volume.
Adjust consistency: Thin the batter with a little water until pourable.
Part 2 — Paneer masala filling
Tempering: Heat ghee in a pan over medium heat. Add mustard seeds and curry leaves and allow them to splutter.
Sauté onions: Add chopped onion and cook until translucent, not browned.
Add spices: Stir in turmeric, coriander powder, Kitchen King masala, salt, and pepper. Cook briefly until aromatic.
Finish with paneer: Add grated paneer and mix well. Lower heat, add lime juice, and combine gently. Keep warm.
Part 3 — Cooking the dosa
Heat the pan: Heat a flat tawa or non-stick pan on medium-high, then reduce to medium. Lightly grease if needed.
Spread the batter: Pour a ladle of batter in the middle of the pan and spread outward in a thin circular motion.
Add filling: When bubbles appear and edges lift, add paneer filling to the middle or one side. Drizzle oil around the edges.
Cook & serve: Cook until the underside is golden and crisp. Fold or roll and serve immediately with coconut chutney.
Tips for extra crisp dosa
Pan must be hot before spreading batter; cook on medium heat after spreading.
Dosas are best cooked on one side only for maximum crispness.
Batter should be pourable and spread easily without tearing.
