Pour milk in a large pan, and cook on high heat. When milk starts boiling, remove from heat. Put a large empty bowl and another one filled with ice the refrigerator. Pour egg yolks and sugar into an electric mixer and mix until it becomes thick and white. Leave aside. Put milk back on heat and bring to boil. Pour a little milk into egg and sugar mix whipping constantly. Pour into milk pan and cook at low temperature stirring constantly with a wooden spoon until firm consistency (about 5 minutes). Do not bring to boil. To check if creme is ready, rub your finger on the back of the spoon and if it leaves a trace, the creme is cooked. Add the pistachio paste. Put the bowl on ice to stop the cooking process. Cover and refrigerate for several hours.
