In a large bowl, add in the flour, and gradually add in the water, while stirring with chopsticks or a fork at the same time. Stir continuously until a shaggy dough forms.
Begin kneading the dough until a ball forms. Keep kneading for another thirty seconds - the dough shouldn't stick to your hands, if it is, add in more flour. Once you've formed a ball of dough, wrap in clingfilm and set it aside while you make your filling.
In a large bowl, combine the finely chopped or ground chicken, chopped spring onions, chopped red onion, chopped coriander (cilantro), grated ginger, minced garlic, garam masala, ground cumin, salt, black pepper, and sugar. Mix thoroughly to combine, then set aside.
Dust your surface with plain flour, then knead your dough for 30 seconds. Poke a hole through the centre of the dough and form the dough into a doughnut shape. Slice through to break the circle and form the dough into a log. Slice the log into 18-20 equal pieces.
Grab a piece of dough, press down on it with the palm of your hand, then using a rolling pin, roll the piece of dough into a circular wrapper around 3 inches in diameter. Repeat for all the wrappers (make sure to not overlap the wrappers as they may stick together, place under a tea towel).
Place a spoonful of the filling into the centre of the wrapper and then pinch the dough and rotate with a pinching motion. Watch the video for a better tutorial. Repeat for all momo dumplings.
Place a circular piece of parchment paper onto your steamer (or individual pieces of parchment paper for each momo), and then arrange your momo into the steamer. Steam for 8 minutes - don't overcook them! Feel free to make the jhol sauce first before steaming them if you want to get that out of the way and focus purely on steaming the dumplings!
Meanwhile, make your jhol momo sauce by frying off your tomatoes in a pan with some vegetable oil on medium heat. After a couple of minutes add in the red chilli, garlic, ginger, cumin seeds, turmeric, and salt. Fry for another 5 minutes, then transfer to a blender and combine with sugar, coriander (cilantro), toasted sesame seeds, chicken broth and lemon juice. Taste and season according to your preference.
Once your dumplings are cooked, divide the jhol momo sauce between 3-4 bowls. Top the sauce with the momo dumplings. Garnish with chili oil and coriander (cilantro). Enjoy!!!
