Milk solids

Use 4 times the weight of milk; simmer and stir continuously in a wide heavy pan until reduced to a dense, fudgy paste.

Use equal weight of finely crumbled or grated paneer mixed with 15% single cream; gives similar body but a less caramelised, milk-solid flavour.

Simmer gently until heavily reduced, or stir in directly at 70% weight; produces rich gravies without the granular bite of khoya.
