Potu is a Chamorro specialty consisting of slightly sweet rice cakes that are flavored with coconuts or tuba, a beverage made by fermenting coconut sap. The secret is to let the rice soak overnight in tuba and then finely ground it the following day.

That same combination is flavored, sweetened, formed into balls or other shapes, then steamed until done. Potu is typically consumed as a breakfast snack, but it is also often present at various Chamorro fiestas.
