In a blending jar, add pistachios, crumbled paneer, milk powder, and milk. Blend until you have a smooth paste.
Transfer the blended mixture to a pan, add green food color, and stir. Cook on medium flame for about 5-6 minutes until it thickens slightly.
Now add sugar and cardamom powder, mix well, and stir continuously until the mixture forms a soft dough.
Add ghee, mix, and stir the mixture until it becomes smooth and non-sticky, resembling playdough.
Take a square or round plate or baking pan, line it with parchment or butter paper, or simply brush and coat the inside with a few drops of ghee.
Drop the cooked mixture onto the plate, spread, and smooth the surface using a spoon or spatula.
Set the plate aside, uncovered, for about 5-6 hours to allow the burfi to set.
Once set, apply edible silver varakh and cut the burfi into square or diamond-shaped pieces using a knife.
Pista Burfi is ready! Garnish with slivered pistachios and store it in an airtight container in the fridge for up to a week. Enjoy!
