Soak the moong for about 4 hours; discard all water, rinse and drain the water again.
Using a food processor or blender, grind the moong with yogurt, garlic, onion, cilantro, jalapeño, and 1⁄2 cup of water to make a thin batter.
Pour into a mixing bowl; egg white, salt, cumin and coriander powder, and 1⁄4 cup of water. Mix well to get consistency of pancake batter. If it is still thick, adjust by adding the remaining water.
In a non-stick medium sized frying pan, over medium high heat, evenly spray cooking spray for 2 seconds. Pour approximately 1⁄4 of the moong batter or 2 oz. and swirl around the pan for an even layer.
Cook 3-4 minutes each side and when flipping over, spray another 2 seconds of cooking oil spray. Dossa should be golden brown when done.
Repeat the same process to make 12 dosas.
Transfer to serving plate and enjoy!
