Enjoy the crispy perfection of Benne 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 the idli rice, urad dal, and poha separately under cool water. Soak rice and poha together in a bowl and urad dal in another for at least 4 hours.
Drain and transfer the soaked ingredients to a blender. Add just enough water to blend to a smooth, pourable batter. The batter should be slightly thick but not dry.
Transfer the batter to a large bowl. Add sugar and salt, mix well, then cover and ferment overnight (8–12 hours) in a warm spot until bubbly and slightly risen.
Heat a nonstick or seasoned cast iron griddle over medium-high. Once hot, reduce to medium. Grease with a few drops of oil.
Pour a ladleful of batter in the center and gently spread into a thin circle. Drizzle 1–2 tsp melted butter around the edge and a bit on top. Cook on medium until the edges turn crisp and the bottom is golden with lacy holes.
Fold and serve hot with more butter if desired. Repeat with remaining batter, adjusting heat as needed to maintain even browning.
