First, take 250 grams or 1/3 cup of prawn. Wash them nicely, remove the shell and the vein from each and chop the meat roughly. Now, put some salt to taste, mix it nicely with the prawn pieces and keep it aside for about 10 minutes to marinate. (Pro tip: You may put a tablespoon of soy sauce for marination).
Now, in a separate mixing bowl, take 1 cup of refined wheat flour (maida), salt to taste and 1 tsp of vegetable oil (or melted butter). Mix everything nicely first.
Now, add water gradually. Knead nicely for 3 to 4 minutes to make a soft dough. Cover the bowl and keep it aside for half an hour to set properly. (Pro tip: The more you knead, the softer will the dough be).
While the dough rests, prepare the ingredients to add to the prawn stuffing. Finely chop ½ cup of onions, ½ cup of capsicum, 2 tbsp of garlic, 3 pieces of chilies, and 3 tbsp of fresh coriander leaves and keep them all on a plate.
Now, heat a frying pan on a medium flame and put 2 tbsp of butter in it. When it melts, put the chopped onions first. Fry them for about 2 to 3 minutes until they turn translucent.
Then, add the chopped garlic and fry them as well for a minute, stirring nicely with the onions.
Finally, add the finely chopped capsicum and green chilies together and fry them on a medium flame for about 2 minutes. (Pro tip: Adding all these ingredients in stages will enhance the taste and allows for perfect cooking).
Now, add the marinated chopped prawns to the mixture.
Fry it for another 2 to 3 minutes or so, until it changes color, as shown in the image below.
Now, add salt to taste and 1 tbsp of soy sauce to it, mix them nicely and cook for another minute or so until it dries up completely. (Pro tip: If you have put soy sauce while marinating the prawns, then there is no need to add any soy sauce at this stage).
When the prawn stuffing is dry, add the chopped coriander leaves and mix them nicely. Switch off the flame of the gas stove and stir it continuously to cool down quickly.
Now, take the dough and knead it for another two to three minutes before making small balls from it. Take one small dough ball to roll.
Roll it into a small puri-like shape.
Take it in your hand and put a little bit of the prawn stuffing at the center. (Pro tip: Do not put too much of stuffing inside, or else it will be difficult to shape the momos).
Fold it to make the momo. You can give any shape you want to your momo.
Repeat the steps to make all your momos.
Now, boil some water and place the momos at a distance in a steamer, greased with a little bit of butter or cooking oil. Cover and let it cook for 10 minutes. (Pro tip: Greasing the steamer with butter or cooking oil is necessary to prevent the momos from sticking to the surface and breaking while removing them. You may use a kadai and a perforated container along with a lid for steaming the momos as well if you do not have a steamer).
After 10 minutes, take them out one by one.
Your homemade tasty prawn momos are ready to enjoy. Arrange them on a plate and serve them along with momo chutney and momo soup.
