The very thought of a dosa, those large thin crispy Indian pancakes, always makes my mouth water. I first tasted them when I travelled to India.
They are made from a batter of ground rice and lentils which has been left to ferment. As large as a dinner plate they are filled with a spicy potato filling and are served with a chutney alongside. They make a nutritious snack at any time of the day but are especially popular as a breakfast food in South India
