Keep a fine mesh strainer over a large bowl and line it with a muslin cloth, paper towels, or a cheesecloth. There should be some gap between the bottom of the bowl and the bottom of the strainer for the liquid to collect.
Add yogurt to the strainer and cover the yogurt with the cloth hanging on the side.
Keep the bowl in the refrigerator for 24 hours to drain.
The excess liquid will drip down in the bowl and you will be left with thick creamy yogurt called chakka.
If using Greek yogurt, you can reduce the straining time to 8-10 hours.
Make The Shrikhand
Transfer the thickened yogurt to a mixing bowl.
Add powdered sugar, ground cardamom, and saffron soaked in milk and whisk using a wire whisk until combined and creamy.
Add nuts and tutti frutti and mix well.
Chill the shrikhand for 2-3 hours for the flavors to mingle well. Transfer it to the serving bowls and garnish with slivered dry fruits. Serve!
You can store it in an airtight container in teh refrigerator for up to 2 weeks.
