Urad Dal Polo with Vegetable Sambar

Grind the Batter

• Drain the soaking water completely from the dal.
• Transfer the soaked dal, chopped ginger, and green chillies to a high-speed blender or wet grinder.
• Add 1/2 cup of fresh water and begin grinding. Scrape down the sides as needed.
• Gradually add more water, a tablespoon at a time, until you achieve a smooth, thick, and fluffy batter. The final consistency should be similar to idli batter - pourable but not watery.

Finalize the Batter

• Transfer the batter to a mixing bowl.
• Stir in the salt and hing (asafoetida). Mix gently until just combined. Do not overmix, as this can deflate the batter.
• Let the batter rest for 10-15 minutes. This step is optional but helps the flavors meld.

Cook the Polos

• Heat a non-stick tawa or a well-seasoned cast-iron skillet over medium heat.
• To check if the tawa is ready, sprinkle a few drops of water; they should sizzle and evaporate immediately.
• Lightly grease the tawa with a few drops of oil using a paper towel or half an onion.
• Pour a ladleful (about 1/4 cup) of batter onto the center of the hot tawa.
• Gently spread the batter in a circular motion to form a small, slightly thick pancake, about 5-6 inches in diameter. Do not spread it too thin like a crispy dosa.
• Drizzle about 1/2 teaspoon of oil around the edges and a few drops on top.

Flip and Serve

• Cook for 1-2 minutes, or until the top surface appears cooked and the edges begin to lift easily from the tawa.
• Using a spatula, flip the polo and cook the other side for another minute until light golden spots appear.
• Fold the polo in half and transfer to a serving plate.
• Repeat the process with the remaining batter, greasing the tawa lightly before making each polo.
• Serve hot with coconut chutney, sambar, or a spicy pickle.

Prepare the Tempering (Tadka)

• In a small pan (tadka pan), heat the sesame oil over medium heat.
• Once hot, add the mustard seeds and wait for them to splutter completely.
• Add the urad dal and fenugreek seeds. Sauté for 30 seconds until the urad dal turns light golden. Be careful not to burn the fenugreek seeds.
• Add the broken dried red chilies, curry leaves, and hing. Sauté for another 15-20 seconds until the curry leaves are crisp and aromatic.

Finish and Serve

• Immediately pour the hot tempering over the simmering sambar. You should hear a satisfying sizzle.
• Stir gently to incorporate the tempering. Garnish with freshly chopped coriander leaves.
• Turn off the heat and let the sambar rest for at least 10-15 minutes before serving. This helps the flavors deepen.
• Serve hot with steamed rice, idli, dosa, or vada.
