Rinse yellow moong until the water runs clear. Soak in warm water for at least 3 – 4 hours. Drain completely and transfer to a high-speed blender with ginger, green chilies, and 3–4 tablespoons of water. Blend into a smooth, thick batter (similar to pancake batter consistency).
1 Cup yellow moong dal, 1 green chilli, 1 inch ginger, chopped, 4 tablespoon water, at room temperature
Pour the batter into a bowl. Whisk in turmeric, cumin powder, asafoetida, rice flour, and salt. Vigorously aerate the batter with a whisk for 5 minutes to incorporate air.
1 teaspoon cumin powder (jeera powder), ½ teaspoon red chilli powder, ½ teaspoon turmeric powder, ⅓ teaspoon hing (asafoetida), ½ teaspoon salt or to taste, 1 tablespoon rice flour (chawal ka atta)
Fold in your chopped vegetables and herbs. And gently mix the batter nicely to combine it all together. Keep the batter aside.
1 small onion, finely chopped, 1 small tomato, finely chopped, 1 small red bell-pepper, finely chopped, handful of fresh coriander leaves, chopped
Right before cooking, mix a pinch of fruit salt or baking soda into the batter. And with light hand, mix the batter nicely. You will notice, it is slowly aerating and becomes light.
¼ teaspoon baking soda
Heat a small non-stick pan over medium heat with 1 teaspoon of oil. Sprinkle a mix of black mustard seeds, white sesame seeds, cumin seeds, and chopped coriander leaves.
white sesame seeds (til), cumin seeds (jeera), sesame oil or vegetable oil, black mustard seeds (rai)
Once the seeds start popping, add a big ladle full of batter into the pan. Evenly spread it. Cover the pan with a lid and cook on medium-low heat for 3–4 minutes until the base turns golden and crisp. Flip gently. Cook uncovered for another 2–3 minutes until both sides are golden brown.
