Take only as much of the mixture as is necessary to make one Adai at a time. Add just enough water to it, mix well and roll it into a ball, about the size of a tennis ball or slightly bigger.
Heat an iron griddle on a medium fire and smear a little oil on it. Place the ball of dough at the centre of the griddle and spread it quickly with the hand into an even pancake, dipping the hand in cold water often.
Pour two or three teaspoonfuls of oil along the edge. Turn it after a minute or two on the griddle. Add a little more oil along the edge and fry for a while till both the sides of the adai turn golden brown in color.
Serve hot with chutney pickle or other side dishes.
