Wash and rise rice. Soak it in water for at least 30 minutes. Use a magic bullet or blender to blend to a smooth paste. You may need to add water if necessary.
Boil milk in a heavy bottom stainless steel pan for about five minutes. Then add your rice paste and whisk until smooth.
After the milk has reduced a bit, add sugar, saffron, and rose water. Keep stirring and cook for about 10-15 minutes until rice has cooked.
Once the firini has a pudding-like consistency, add cardamom powder and mix.
Remove from heat and allow to cool in serving bowls.
Serve chilled. Garnish with ground pistachios.
