Rinse the glutinous rice with water, then drain in a colander.
In a heat-proof bowl, combine the rinsed rice and one cup of coconut milk. Steam the rice over high heat for 45 minutes, or until all the coconut milk has been absorbed into the rice.
Using a food processor or blender, pulse the durian until creamy. Add in one to two tablespoons of sugar to taste, then pulse a few more times till well combined.
Dish out the cooked rice into two bowls and top with the durian puree. Serve with more coconut milk poured over the dish.
