Bring 2 litres of water to a rolling boil in a large saucepan, then add 6 unpeeled green bananas and boil for 20 minutes until tender. Drain thoroughly and leave to cool slightly.
Whisk together 1014 g plain yogurt, 4.2 g granulated sugar, and salt to taste in a bowl until smooth, then set aside.
Peel the cooked bananas and briefly pulse them in a food processor. Transfer to a mixing bowl and mash thoroughly with a fork, then fold in 6–12 g green chilli, 0.7 g coriander leaf, and the dumpling spices until evenly combined.
Divide the banana dough into 20 equal portions, roll each into a smooth ball, and flatten gently between your palms into thick discs.
Heat 310 g ghee in a kadhai or heavy-based deep pan over medium-high heat until it reaches 180°C (356°F), or until a bread cube browns within 40 seconds.
Fry the dumplings in batches for roughly 3 minutes, turning once halfway through, until crisp and golden brown on both sides.
Remove the dumplings with a slotted spoon, drain on paper towels, and dust with a pinch of salt to taste.
Immerse the warm dumplings in the whisked yoghurt sauce, ensuring each one is fully coated, and serve.
Use 120% of the weight; melt gently over low heat to avoid burning the milk solids, which will yield a softer, creamier richness rather than a nutty aroma.
