Pour the soaked moong dal into a wire strainer, rinse, and drain well before blending it in a food processor with 2. 33 tbsp (1. 2 oz / 35 g) water for about 4 minutes until it becomes a fine, airy batter.
Scrape the batter into a bowl, transferring 0. 33 cup (2. 7 oz / 80 g) into a separate large saucepan to reserve for the sauce, and whisk the remaining batter with 0. 5 tsp (0. 1 oz / 3 g) salt, 0. 5 tsp (0. 1 oz / 1. 5 g) turmeric, 1 tsp (0. 1 oz / 2 g) cumin seeds, 0. 25 tsp (0. 05 oz / 1 g) pomegranate seeds, and 0. 125 tsp (0. 02 oz / 0. 5 g) baking powder to make it light.
Heat ghee in a frying pan to 340°F (170°C) and drop 0. 5 tsp (0. 08 oz / 2. 5 g) dollops of the batter into the hot oil, frying until golden brown, then transfer them into 4 cups (33. 8 oz / 1000 g) of warm salted water to soak for 15 minutes before gently pressing them between your palms to squeeze out the liquid.
Whisk 1. 75 cups (14. 8 oz / 420 g) plain yogurt, 2. 75 cups (22 oz / 650 g) water, 1 tbsp (0. 3 oz / 8 g) chickpea flour, 0. 5 tbsp (0. 15 oz / 4 g) turmeric, and 0. 125 tsp (0. 03 oz / 0. 5 g) paprika into the reserved dal batter in the saucepan, bring to a gentle boil over moderate heat, then add 10 curry leaves and 1 tsp (0. 2 oz / 6 g) salt, simmering for 15 minutes before adding the soaked dumplings to simmer for a final 3 minutes.
Heat 2 tbsp (1 oz / 28 g) ghee in a small pan until hot, add the green chilies, 2 tsp (0. 3 oz / 10 g) minced ginger, 1 tsp (0. 1 oz / 2 g) cumin seeds, 0. 5 tsp (0. 1 oz / 2 g) mustard seeds, and 0. 5 tbsp (0. 25 oz / 7 g) raw sugar, stir-fry until the spices brown, then pour this tempering directly into the karhi, cover to trap the aroma, and fold in 2 tbsp (0. 2 oz / 5 g) coriander and 1 tsp (0. 17 oz / 5 g) lemon juice just before serving.
Squeeze Gently: When removing the fried dumplings from their warm water soak, press them between your palms with very gentle pressure. You want to extract the water without breaking the delicate structure of the dumplings.
