Stir in the turmeric and cumin and then add about half the base sauce. Bring this to a rolling simmer, stirring only if the sauce is obviously sticking to the pan.
Add the pre-cooked chicken and stir it into the sauce.
Now Add the mango chutney, mint sauce and ketchup and bring to a simmer adding more sauce gradually.
When the pathia sauce has cooked down to your preferred consistency, add the single cream and red food colouring, if using.
