Ingredients
Method
Mix dry ingredients, onions, spices.
Add water gradually to very thin, watery batter.
Rest 15–20 min, rava absorbs water, add more if needed.
Heat tawa quite hot, stir batter well before each dosa (rava settles).
Pour from edges inward, don't spread much, batter will form lacy holes.
Drizzle oil, cook until deep golden and crisp. No need to flip. Serve hot.
Notes
Batter must be watery like buttermilk. If dosa is thick, add more water. Don't add too much onion or it sticks.
