Soak rice for at least 3 hours and even overnight.
In a large pot or a wok, add a steamer stand and place bamboo steamer on top. Fill pot with boiling water enough to come up sides of steamer without going into steamer compartment.
Place rice in aluminum foil and put in steamer. Cover and cook for about 40 minutes.
Using a large spatula, carefully flip over and cook another 30 minutes.
