Place a muslin cloth on a bowl and pour the yogurt. Bring all the edges of the muslin cloth together. Tie the muslin so that it can hang and the whey can drip. Alternatively, you can place the muslin cloth on a strainer and place the strainer on the bowl
Place it in the refrigerator for a minimum of 4-5 hours or overnight
Next morning all the whey or liquid will be drained and you will get hung curd (you can use the whey in cooking as it is very nutritious)
Slightly warm the milk and add saffron to it. Let it sit for a few minutes
Transfer the hung curd into a bowl. Add powdered sugar and saffron milk. Mix gently
Add the sliced nuts and mix gently (take care not to over-mix it)
Serve chilled
