1 cup urad dal/black lentils (split or whole, with or without skin)
500mL water + 2.5 Liters + additional 500mL for dosas
4 cups rice flour
1 teaspoon fenugreek seed powder, freshly ground
1 1/2 teaspoon kosher sea salt
1/2 teaspoon yeast
1 cup chopped tomatoes
1/2 cup red onion chopped
1/2 cup cilantro leaves, freshly chopped
1/2 teaspoon chili powder
1/2 teaspoon roasted cumin, freshly ground
1/2 teaspoon kosher sea salt
vegetable oil for cooking (vegetable oil sprays are also pretty useful here)
Clean the lentils to remove any stones that might be present. Rinse under running tap water, place in a large bowl, cover with water and soak overnight. The next day drain the water and grind the lentils with the 500mL of water to a smooth paste with a blender. There should be no clumps in the batter. Transfer to a bowl and cover and let it sit for at least 12 hours or at this point you can either refrigerate the lentil mixture and use it within 2-3 days.
The next day transfer the lentil mixture to a large mixing bowl. Add the flour, fenugreek powder, salt and yeast. Add the half of the 2.5 Liters of water to batter and stir to form a smooth batter. Transfer the batter to a large container or stockpot (one with deep bottom will be useful when the fermentation causes the batter to rise and prevent it from overflowing. Allow the batter to sit covered (not airtight) for at least 6 hours before using. The batter will ferment and rise.
On the day of cooking, mix the tomatoes, onions, cilantro, chili, cumin and salt in a medium bowl and keep aside. (This will be used to top the uttapams)
To prepare Uttapams: Heat a large non-stick pan or cast iron skillet on medium-high. Pour and spread a teaspoon of oil on the surface of the pan. The batter will be thick resembling the consistency of a pancake batter. Pour about 1/2 cup of the batter in the center and allow it to spread by itself into an 8 inch circle. Sprinkle about two generous tablespoons of the mixed tomato-onion mixture over the top of the uttapam and then drizzle with 1/2 teaspoon vegetable oil. Cook until the edges get golden brown and they start to come off from the sides. Using a silicone spatula, release the uttapam from the sides, and flip to cook on the other side for about 1 – 1 1/2 minutes. Prepare the rest similarly. Serve hot.
To prepare Dosas: Add 500mL of water to the batter and stir. The consistency should be thinner like that of a crêpe batter. Heat a large non-stick pan or cast iron skillet on medium-low. Pour and spread a teaspoon of oil on the surface of the pan. Using a ladle pour about 1/2 cup batter in the center of the oiled pan and spread the batter with a circular motion using the ladle starting from the center moving outwards to form a large thin crêpe (don’t use too much pressure or it will tear the dosa as it begins to cook). Drizzle about 1/2 teaspoon oil over the dosa. Cook until the dosa begins to turn golden brown and begins to leave the sides of the pan. Using a silicone spatula, release the uttapam from the sides, and flip to cook on the other side for about 3 minutes. Prepare the rest similarly. Serve hot.
