1.All the ingredients listed can be combined at one shot and cooked, I did step by step as it easy to mix milk powder
2.Using nuts is optional, it gives nice crunch to the kulfi
3.Saffron can be added while boiling the milk but I preferred adding it towards the ends so it won't change the kulfi color
4.Kulfi can be refrigerated for 5 minutes and unmold
5.Enjoy kulfi immediately after un molding else it night become watery
6.If you prefer to reduce cooking time increase the milk powder ratio
