Oca is an incredibly popular tuber in South America (it's
second only to the potato as the favorite root vegetable in
Bolivia and Peru). In the United States, however, oca is widely
ignored, but growing in popularity among specialty shops and
Oca can taste tangy (like a lemony potato) or sweet
(like an apricot) depending on its variety.
What exactly is oca? It's a perennial plant whose tubers
are similar to potatoes, only with wrinkles and very brightly
colored in red, orange, yellow, purple and pink. Depending
on the variety -- there are over 50 -- they have a flavor
ranging from a lemony potato to a sweet chestnut (they're
also sometimes described as "potatoes that don't need
Unlike potatoes, oca can be eaten raw, but they're also delicious
boiled, baked, steamed, stewed, grilled, fried or candied.
The Lost Food of the Incas
Oca is sometimes referred to as one of the "lost crops
of the Incas," because, despite its potential to become
a globally cultivated crop, it's still mostly enjoyed only
in a few limited areas, namely South America, Mexico and New
Zealand (where it's called the "New Zealand yam").
Thought to be one of the oldest crops of the Andean region
(tubers were even found in early tombs in the area), the oca
suffers unfairly from the stigma of a "poverty food,"
yet supplies a rich source of carbohydrates, calcium and iron
(some high-protein varieties even contain more than 9 percent
protein), not to mention great taste and versatility.
Watch out for oca's other names: ocha, the New Zealand
yam, quiba, hibias, timbo, apilla and papa roja.
Consider these varied samplings of how the oca is prepared:
In Mexico, oca is often served raw with salt, lemon and
hot pepper added
Oca can be pickled and made into bottled preserves
In the Andes, oca is dried in the sun, which makes it
Oca is often baked and stewed
Where to Find Oca
You can grow your own oca if you're up for a challenge. It's
an incredibly hearty plant (with very attractive leaves and
flowers) that is harvested in the winter. Alternatively, you
can keep a watch out for brightly colored tubers that resemble
small, wrinkled carrots at specialty markets. If you spot
them, you've found oca.
If you get your hands on some oca, try it prepared simply,
such as baked or boiled like a potato, or if you're in the
