To prepare these delicious burfis, soak the pistachios in warm water for about 20 minutes.
Drain the water and remove the skin of the pistachios. Add the pistachios and 2- 3 drops of food color in a mixer to blend them to form a smooth paste.
Then, prepare a sugar syrup by dissolving the sugar in the water.
Add the pista paste to the sugar syrup and keep stirring. Add the cardamom powder and cook for a few minutes.
Grease a plate using the ghee and spread the pista mixture on it. Allow it set for about an hour.
Then, cut into desired shapes and garnish with the silver vark. Serve.
