Soak 1/2 cup small Basmati rice in adequate water for 15 to 20 minutes after rinsing it twice in fresh water.
Heat 1.5 litre of fat milk in a large, wide pan or Kadai.
Stir at regular intervals on low flame to prevent the milk from burning and sticking at the bottom of the pan.
After the milk starts to boil, strain the rice and add it to the boiling milk. With the help of a spatula, thoroughly combine the ingredients.
On low heat, simmer and cook the rice.
Cook the rice grains until almost done. Add in 4 to 6 tablespoons sugar, and stir as and when needed.
Cook the rice over low to medium-low heat. Stir at regular intervals. Add more boiled milk if required.
Cook until the rice grains are almost done.
After that, stir in 1/4 teaspoon green cardamom powder.
Add 1 tablespoon sliced almonds, chopped cashews, raisins, and sliced pistachios.
In separate serving bowl, serve the Rice Kheer hot or cold after topping it with nuts of your choice.
