Heat 1 cup of water and jaggery in a saucepan. Boil for 5 minutes and strain to remove any residue. Keep it aside.
Heat one tablespoon of ghee in a pressure cooker over medium heat. Add chopped nuts and roast until the colour changes to light golden. Turn off the heat and keep the roasted nuts aside.

Heat the ghee in a pressure cooker, add the broken wheat and saute on a medium flame for 5 to 7 minutes or till it turns light pink in colour.
Now add remaining 2 & 1/2 cups of water with strained jaggery water and chopped dates. Pressure cook on a high flame for 4 whistles.

Allow the steam to escape before opening the lid.
Now add the chopped dry fruits, salt, cardamom powder, fennel and pour remaining 1 tbsp of ghee over halwa. Serve hot.

Tips:

Amount of water will depend on the variety of broken wheat.
White sugar or brown sugar can be used instead of jaggery.
