Make the dough: In a bowl, mix flour and salt. Add warm water gradually and bring it together into a dough.
Knead for 6–8 minutes until smooth and elastic. Coat lightly with oil, cover, and rest for 20–30 minutes.
Prep the filling: In a mixing bowl, combine ground chicken, onion, cabbage, scallions, ginger, garlic, chilies, soy sauce, sesame oil, pepper, salt, and 1 tablespoon neutral oil. Mix gently until evenly combined but don’t overwork it.
The mixture should be cohesive and slightly sticky.
Make the chutney (optional): Char or roast the tomatoes in a dry pan until blistered, or boil for 3–4 minutes. Blend with soaked chilies, garlic, sesame seeds, soy sauce, salt, and lemon. Add a splash of water to reach a spoonable consistency.
Set aside.
Shape the wrappers: Divide the dough into 20–24 small balls (about 1–1.5 inches each). Keep covered with a damp cloth. Roll each ball into a thin circle, about 3 inches wide, slightly thicker in the center.
If the dough sticks, dust lightly with flour.
Fill and fold: Place 1 tablespoon of chicken filling in the center of a wrapper. For the classic pleated shape, pinch a small fold on one edge and continue pleating around, sealing at the top. Or go simple: fold into a half-moon and pinch edges tight.
The key is a good seal so juices don’t leak out.
Prep the steamer: Line the steamer with parchment with holes or lightly oil it to prevent sticking. Bring water to a rolling simmer.
Steam the momos: Arrange momos with space between them. Steam for 8–10 minutes, or until the wrappers turn slightly translucent and the chicken is cooked through.
If you cut one open, it should be juicy, not pink.
Optional pan-fry (for crispy bottoms): Heat 1 tablespoon oil in a nonstick skillet on medium. Arrange momos, brown the bottoms for 1–2 minutes, add 1/4 cup water, cover, and steam until water evaporates, about 5–6 minutes.
Serve: Plate the hot momos with chutney and a side of soy sauce or chili crisp if you like extra heat.
