Add the black gram and cook on a medium flame till the grains are just a little tender and begin to split.
Add the tomato paste, tomato puree, and cream, simmer (adding hot water if necessary) for 2 hours or more till the black gram is soft and the mixture turns a rich red in colour.
Heat the ghee in a wok (kadhai), sauté the ginger and add to the black gram mixture.

Serve hot garnished with a swirl of cream.
