Grate the carrots.
Place the kadai/deep bottomed pan on the gas.
Add 1 spoonful of ghee.
Add grated carrots and powdered cardamom and fry for a few minutes.
Add enough milk to soak the carrots and allow it to get cooked in medium flame.
Once the carrot absorbs all the milk add broken jaggery and stir it well till the jaggery melts and starts cooking with carrots.
Keep stirring constantly in medium flame. Add some ghee if the stirring gets tough till the halwa leaves the side.
Switch off the gas and remove it from the stove.
Garnish with pistachios and raisins.
Serve hot.
