Dosas are a specialty of southern India. Our spicy rava dosa, made with semolina and yogurt, is unfilled and served with sweet, piquant coconut chutney and steaming chai tea.
Stir together flour, yogurt, chiles, ginger, curry leaves (if desired), cilantro, and 3/4 teaspoon salt. Stir in 2 to 2 1/2 cups warm water until batter has consistency of heavy cream. Cover; let stand 1 hour.
Heat a large nonstick skillet over medium- high heat. Oil surface. Pour in about 1 cup batter, swirling to cover bottom of pan. Cook, flipping once, until golden brown, 3 to 4 minutes per side; season with salt. Repeat with remaining batter. Fold into thirds lengthwise; transfer to serving plates. Serve with chutney.
