Take 2 cups of rice in a bowl, rinse it out until the water is clear. Once done, add water to soak the rice. There must be 1 inch of water above the rice.
In a separate bowl, add methi seeds. Add enough water to soak them.
Soak both of them separately for a minimum of 4 hours and a mzaximum of 8 hours.
Once soaked, add the soaked methi seeds along with the water to a grinder or mixer. Keep it grinding until the methi seeds fluff up during the grinding process.
Next add the soaked rice with a little water. Use cold water to grind the rice and methi together.
Transfer the batter to a separate container, add rock salt and mix with you hand.
Allow it to ferment for 6-8 hours until you see tiny bubbles on top.
Add some water to thin down the batter and you can now make your Methi dosas.
Pour a large ladle of Methi Dosa batter and gently spread it on a preheated tawa. You will see small holes appear in the dosa. Place a lid on top of the dosa and allow it to steam cook. You will not need to cook on both sides since you are steaming cooking. Drizzle some cooking oil around the dosa and cook without the lid for thirty seconds. Remove from the tawa and serve with a chutney of your choice.
