In a saucepan bring to a boil: rice, coconut milk, salt, sugar and 1 1/4 cup water. Stir.
Lower heat and simmer, uncovered, about 8-10 minutes until all the liquid is absorbed. Remove from heat.
Cover and let stand 5 minutes.
Transfer rice to a steamer or double saucepan and steam 15-20 minutes over boiling water, until rice is cooked through.
Mold the cooked rice into individual ramekins or small cups lined with plastic wrap.
Cool to room temperature.
At serving time unmold onto a plate and top with mango or even strawberries.
