Oca can be used as a potato substitute. The skins of Oca are thin, like new potatoes, and do not need to be removed to cook. Oca can be used in cooking similarly to the potato, but is sweeter. The Oca tubers become sweeter when exposed to sunlight for a few days after harvest (protect from frost). There is no danger of Oca âgoing greenâ, as Oca is unrelated to the potato.
