Pour a little oil into the pan and tilt it to cover the base
Fill the ladle up to the 3/4 level with dosa batter. Gently pour this batter onto the centre of the pan - just as you would for a pancake
Now begin to spread the batter in sweeping circular motions to cover the base of the frying pan. The dosa may have little holes- this is normal
When the upper surface begins to look cooked (it will no longer look soft or runny), flip the dosa. By this time, ideally, the surface that was underneath should be light golden in colour. Cook for 1 minute after flipping.
The dosa is almost done. Fold it in half and allow to cook for 30 seconds more
