Chop the nuts and get it ready. I had some leftover nuts powdered after making this ladoos so used that also, but that's purely optional.
Take a pan - add milk and simmer it till it is reduced to almost half. It may take at least 20mins so keep stirring in between so that it doesn't get burnt at the bottom.
Now add condensed milk to it and whisk it well. Keep stirring to avoid burning at the bottom.
Crush saffron strands and add it. The color of milk will change to slightly yellow color, after saffron is added, let it boil for at least 5-7mins in low flame.
You can see malai forming, Keep stirring. Now add sugar and whisk it well. Scrape the sides.
Once milk is thick and creamy with malai formed add the nuts and let it simmer for 2mins.
Add nuts powder along with cardamom powder.
Once it is thick and creamy switch off. As it cools downs it may get more thick.
Chill it for at least an hour and enjoy Basundi!.
