Mix everything. 

Cook for 10 minutes, until the tomato purée is cooked and sauce is finely mixed. 

Add some hot water if necessary to maintain the consistency of the sauce and prevent it from drying. 

Mix well and stir continuously to prevent the sauce from burning. 

Mix 3 tablespoons of curry powder into the tomato sauce. 

Mix well and cook for 5 minutes or until the powder is well incorporated into the sauce and is cooked. 

Add some hot water if necessary to maintain the proper consistency of the sauce.

If you like curry sauce, add hot water gradually until it is to your liking. 

Transfer to a plate. 

Garnish with fresh coriander leaves.
