Firstly food colour is totally optional and you can take yellow colour also instead of orange. You can even use soaked saffron for colour. Now in a pan add water, sugar, food colour and cardamom powder and mix well. Keep the pan on high heat and boil until the sugar dissolves then cook for 2 more minutes and off the flame. Then add milk followed by dry fruit mix to sugar syrup and mix well. Wash and peel the apple then grate it with a grater and add to the prepared liquid. Mix them all well.
