Chuno
Chuno is a freeze-dried potato product traditionally made by Quechua and Aymara communities of Peru and Bolivia , and is known in various countries of South America, including Peru, Bolivia, Argentina, and Chile. It is a five-day process, obtained by exposing a frost-resistant variety of potatoes to the very low night temperatures of the Andean Altiplano, freezing them, and subsequently exposing them to the intense sunlight of the day (this being the traditional process). The word comes from Quechua ''ch'unu, meaning frozen potato(wrinkledin the dialects of the Junin Region).
Origins
The existence of chuno dates back to before the time of the Inca Empire, based on findings of that have been made of the product at various archeological sites. Specifically they have been found at Tiwanaku, site of a culture which developed in the Collao Plateau, a geographic zone which includes territories of Peru and Bolivia.
Production
After harvest, potatoes are selected for the production of chuno, typically small ones for ease of processing. These small potatoes are spread closely on flat ground, and allowed to freeze with low night temperatures, for approximately three nights.
Between the freezing nights, they are exposed to the sun, and they are trampled by foot. This eliminates what little water is still retained by the potatoes, and removes the skins, enabling subsequent freezing.
After this, they are exposed to the cold for two additional nights.
Starting from this basic freeze-dry process, two varieties are obtained:
White chuno
White chuno is obtained by "washing" the frozen potatoes. The "washing" may take various forms. In Peru, the frozen potatoes are transported to a river, and deposited in pools. In Bolivia, the potatoes are spread on blankets or straw and constantly sprayed with water to moisten them.
The final step is drying in the sun. The result is now called chuno, also known as papas secas''. In Bolivia, white chuno is also called tunta. Among the varied uses of tuntas in traditional cuisine, one is as an accompaniment to Christmas celebration dishes. Called "picana", the tunta is cut in the middle, a piece of white cheese is inserted, and it is steamed.
Black chuno
Black chuno is that which is obtained directly from freezing, trampling, and refreezing. The product is not washed or exposed to water again; after freezing and trampling it is simply sun-dried.
Preservation and consumption
Once dried, and with minimal care in storage, the product can last for a long time, even years.
Consumption is varied, from desserts to prepared dishes, as well as chuno flour, which is an essential ingredient in many dishes of Peruvian cuisine. Chairo is one of the most traditional Bolivian soups and it is made with chuno, meat and lots of vegetables, it is also traditional in Southern regions of Peru like Arequipa and Puno.
