Munini-imo (or muninimo, from Ainu ''munin'' ["fermented"] and Japanese ''imo'' ["potatoes"]) is a dish of the Ainu people of Northern Japan. It is a savory pancake made with potato flour. Potatoes are first fermented underground by the repeated freeze-thaw cycles, and then milled and dried. The flour is soaked in water in order to remove the bitter taste and then baked on a griddle like a thick pancake. The potato flour made with this process can be easily stored for at least twenty years. The ''munini-imo'' is very sticky like Mochi (food), ''mochi''.
