Soak rice for 1/2 hour.
Bring 1 1/2 cups water, coconut milk, and ginger to a boil.
Add rice and bring to a boil again.
Reduce to a simmer, cover, and cook on medium-low heat for 20 minutes, until rice is tender and the liquid has been absorbed.
Heat oil in a wok or large pot.
Add mustard seeds. When they start to pop, add chiles. After 1 minute, add sesame seeds.
When the sesame seeds turn golden brown, add coconut, salt, and rice.
