Enjoy the crispy perfection of Paper Dosa, a classic South Indian fermented crepe with a golden, lacy texture. This vegetarian breakfast favorite is protein-rich and loved by the whole family.
Rinse parboiled rice, urad dal, and poha thoroughly, then soak them separately in enough water for at least 4 hours at room temperature.
Drain the soaked ingredients and combine them with 1.25 cups water in a blender; grind to a smooth, slightly thick batter (aim for a pourable but not watery consistency).
Transfer the batter to a large bowl, cover loosely, and let it ferment in a warm spot for 8–12 hours, until bubbly and airy.
Gently stir in salt and 1 cup water to adjust dosa batter to a thin, spreadable consistency just before cooking.
Heat a cast iron or nonstick skillet over medium-high heat, lightly grease with a few drops of vegetable oil, then pour a ladleful of batter in the center. Immediately spiral outward with the ladle to create a super thin, lacy round.
Drizzle a few drops of oil around the edges, cook on medium-high until the edges lift and dosa turns crisp and golden. No need to flip—remove carefully with a spatula and serve hot.
