The dosa, a pancake-like crepe originating from India and made with rice flour batter. It is traditionally served as an appetizer to most Indian meals although more recently it has expanded in popularity around the world. The main ingredients are fermented black lentils and rice which make up about half of the mixture's volume before fermentation begins (depending on what type you're making).
The traditional preparation process starts by combining these two grains together first until they form a fine smooth paste that can be rolled out into thin circles or shaped like rectangles without any cracks appearing when tested for doneness by pressing your thumb lightly across its surface while cooked but not yet browned in oil heated over medium heat below frying temperature - if there is cracking then the batter is too thick.
