Heat the milk in a heavy bottom nonstick pan on a high to medium heat. Stir occasionally and make sure that the milk doesn’t stick to the bottom.
Let it boil, stirring occasionally. After 2 hours the milk will reduce in half.
Let the milk reduce. When it gets little thickened reduce the flame over low to medium heat and stir continuously.
Stir until the milk becomes little bit solid like very soft dough. And it is ready.
