Cook the beef by adding 1 tsp pepper powder, 1/4 tsp turmeric powder and salt as required.
Take a bowl and add cooked and shredded beef.
Add chopped onion.
Add chopped coriander leaves and pepper powder.
Add soya sauce and salt as required.
Pour the flour, salt and oil into a mixing bowl and begin kneading and forming a dough. It will be quite dry at first but eventually form into a nice, soft dough. Continue kneading for about 10 minutes until you have a soft, non sticky dough. Allow to rest, cover with a damp cloth for about an hour. Take a small portion of dough. Flatten and roll out into a thin round shape and cut it with the help of a cookie cutter to get a perfect shape, it is optional.
Place a tablespoon of filling on top of it and fold all the sides into center portion like shown in the figure.
Stem the momos for about 5-6 minutes. They should not be touching when steaming.
Enjoy with soy sauce or another sauce. Hot sauce is also good with these.
