Soak Reem ka Steam Basmati Rice for 15 minutes. Then grind to very smooth paste
In a heavy bottom pan add milk, bring to a boil and let simmer for 10 minutes. Add ground rice to it stirring constantly to avoid any lumps. Reduce heat and let simmer for another 10 minutes. When it starts to thicken add cream, sugar, cardamom powder and saffron strands (if using)
The mixture will start to thicken. Taste check and adjust sweetness (sugar) according to your liking. The consistency of Firni shouldn't be too thick or too runny. Take out Firni in serving bowls and chill refrigerator for 1-2 hours
In another pan, caramelize castor sugar (be careful not to burn it). Add chopped nuts and mix until well coated
Now pour the nutty caramel mixture on a silicon sheet and spread evenly. If you don’t have a silicon sheet, grease a baking tray with clarified butter and spread the nutty mixture on it. While the mixture is still hot, using a cookie cutter make round impressions on it so that it’s easier to shape the discs. Let it cool completely on room temperature and then take out the discs.
To Serve - Top Firni with Nutty Caramel Disc and serve
