In a large pan, whisk the hung curd and condensed milk together with a electric hand blender till it's smooth and creamy. Add the milk slowly and whisk again till you see the froth appearing.
Add cardamom powder and handful of raisins and give a quick stir again.
Preheat the oven at 180 degrees celsius and meanwhile take 6 ramekins or earthen ware or any oven safe bowl in which you want to bake the curd. You can also bake it in a large baking tray and later cut into pieces.
Pour in the curd mix into the ramekins till the rim. In a baking tray or a drip tray of the oven , place the filled ramekins and pour water in the tray till the ramekins are half immersed.
Place the tray in the oven and bake for 40-45 mins or till the tooth pick inserted comes out clean. The baking tie may vary from oven to oven.
Take out the tray and let it cool. Once the ramekins are cooled completely, garnish it with chopped pistachios, strawberries or any fruit or nuts.
