In a wide and deep cooking pot, heat butter or oil. Add cinnamon stick and peppercorns first. Next saute the onions and garlic for atleast 2 minutes.

Add rest of the ingredients now including water. Cover it with a lid and let it simmer on low flame for atleast an hour until the meat becomes tender and the soup gets thicker. The more the amount of oats added,the thicker the soup will get. So add it according to your choice. If you do so, then increase the amount of water and the other ingredients too. See to it that it is simmered on a low heat. Oats render the thickness to it.

Keep stirring it at regular intervals to avoid it from burning or sticking to the bottom. For a change, you can also add any of your favourite veggies. Traditionally, it has nothing but meat and oats. But I do add some veggies always. (like those of green peas and sweet corn)

Adjust salt according to taste. Serve it piping hot garnished with freshly chopped coriander leaves.
