A mixture of rice and blak gramsthat has been soaked in water is ground finely to form a batter. Some add a handful of fenugreek seeds soaked along with the rice. The proportion of rice to lentils is generally 4:1 or 5:1. The batter is allowed to ferment overnight. After the overnight fermentation, the batter is mixed with water to get the desired thickness. The batter is then ladled onto a hot tava (griddle) greased with oil or ghee (clarified butter). It is spread out evenly with the base of a ladle or bowl to form a pancake. A dosa is served hot, either folded in half or rolled like a wrap. It is also usually served with chutney and sambar. The mixture of black grams and rice can be replaced with highly refined wheat flour or semolina.
