Wash and rinse the rice. Soak for 30 minutes.
Remove the cardamom seeds from the cardamom pods, and lightly crush in a mortar and pestle.
Place milk, water and cardamom seeds in a heavy bottomed pot and bring to a gentle simmer (should be hot but not boiling). Drain the water from the rice and add it to the milk.
Cook the rice and milk mixture on low simmer for around 1 hour. Once the rice is soft, stir vigorously with a whisk to mash the rice and break into small pieces. An immersion blender can also be used for a few seconds to break the rice up.
Make sure to keep stirring every few minutes so the milk doesn’t scald on the bottom of the pot. As the kheer cooks, a layer of milk skin (known as malawill form on the top of the milk - it can be removed but I mix it in as it adds texture to the kheer.
The longer the kheer cooks, the milk will reduce further and the texture will get thicker. So adjust cooking time based on preferred consistency.
Add the sugar, and cook for another 10 minutes making sure to stir every 1 - 2 minutes.
Add 1 tablespoon sliced pistachios and 1 tablespoon sliced almonds, and stir through. Any additional flavourings can also be added at this stage.
Cook for a few more minutes, and turn off the heat.
Kheer can be served warm or cold. Most people prefer it cold.
The kheer will thicken further as it cools, so pour it into the desired serving bowls to set. Garnish with remaining pistachios and almonds. I decided to decorate one bowl with sliced almonds and edible rose petals.
Let the kheer come to room temperature, and then chill in the fridge.
