Transfer the rice to a large pan and pour in the water.
Add pandan leaf now, if using.
Cook on medium heat, check the rice constantly.
As the last bit of water evaporates, lower the heat.
Let the rice overcook so it becomes soft and mushy.
Pour in the coconut milk and add the salt.
Check if the salt is adequate.
Maintain low-medium heat to avoid the rice sticking to the pan, stirring occasionally.
Cook on low heat for 10 minutes or until the rice has a soft creamy, porridge-like consistency.
Take the pan off the heat and let it cool for 2-3 minutes.
Line a cake pan with plastic wrap and pour the rice in.
Gently even out and flatten the rice to take the shape of the pan.
