Turn off the flame when the mixture gets thick and stops sticking to the bottom of the pan.
Transfer halwa to a wide plate or bowl and let it cool.
Serve warm or at room temperature.
Notes
The Colour of the halwa depends on the quality of your saffron. If desired, add some food colour for a brighter halwa. You can add anywhere between 3/4 - 1 cup sugar depending on your taste.
