Indian Cooking Recipe : Pista Barfi Ingredients : ¾ cup pistachios 2½ cup whole milk 1 tsp rose water 2 drops food coloring (green) ½ cup water 5 tbsp light brown sugar Method : In a heavy based pan, place the milk over low heat. Stir occasionally for 1 hour until the milk reduces its original volume by 1/6th. Roast the pistachio nuts and cut them. Mix the water & sugar. Heat them to make a thick syrup. Cover and keep aside. Now, put the sugar syrup, roasted pistas, rose-water and green coloring to the reduced milk. Stir until the mixture holds together without sticking to the pan. Spread the mixture in a greased tray. Allow it to stand for about 45 minutes to set, then cut into squares.
