Ingredients

• 3 cups uncooked rice
• 1 cup urad dal ( Black gram)
• 2 teaspoons fenugreek seeds
• 6 cups water
• salt to taste
• 6 tablespoons cooking oil, divided
• 6 teaspoons butter, divided

Directions

• Rinse the rice and urad dal in a mesh strainer. Place it in a bowl and add fenugreek seeds. Soak it in water for 2 to 4 hours. While draining it afterward, reserve some amount of water.
• Grind rice and urad dal in a blender using enough reserved soaking water to reach the consistency of cake batter. Mix in salt, cover and place the batter in a warm spot until it is fermented and starts rising. Stir fermented batter gently.
• Heat 1 teaspoon oil on a griddle over medium heat and wipe it quickly with a wet cloth to diffuse heat.
• Spread a large ladleful of batter quickly, thinly, and evenly over the griddle using the back of the ladle. Increase heat to high. Spread 2 teaspoons of oil on the surface of the dosa, cover it and cook for 1 or 2 minutes until the top is spongy.
• Remove the lid and cook for a minute until the bottom is crispy. Spread 1 teaspoon of butter on top of the dosa and transfer to a plate.
