Rinse the rice with cold water three times and set it aside to drain.
Using a small saucepan, combine coconut milk, half a cup of water, salt, and sugar.
Mix until the sugar has dissolved.
Place the saucepan over medium heat, cover with a lid and bring to a boil.
Add the rinsed (and drained) rice.
Mix to even out the rice in the pan and cover with a lid again.
Adjust heat to medium-low and simmer until the rice is cooked. It generally takes 25 to 30 minutes.
When the rice has absorbed all the liquid, use a fork to mix the rice lightly. Do this only once or twice, not repeatedly.
Take the saucepan off the heat and keep covered for about five more minutes.
Transfer your coconut rice into plates and serve, garnish with coriander leaves, if preferred.
