Discover Peru

When people find out I’m Peruvian, the questions usually start with Machu Picchu or ceviche. Which I love. But if I really want to explain where Peru’s relationship with food comes from — the depth of it, I start somewhere much humbler.

I start with the potato. This is the Peruvian Potato history.

Not the supermarket potato. The Peruvian potato: nearly 4,000 native varieties growing between 2,000 and 4,500 metres above sea level, in colours that look almost impossible for a vegetable — deep purple, mottled red, bright yellow, near-black. Each one carrying thousands of years of Andean knowledge behind it. And a story that, once you know it, changes how you look at a plate of mashed potatoes anywhere in the world.

10,000 Years of History Underground

The relationship between Andean peoples and the potato began more than 10,000 years ago along the western edge of what is now Peru and south-western South America. But it was around 8,000 years ago, in the Lake Titicaca region, that cultivation and conservation techniques were truly refined. The oldest archaeological remains of cultivated potatoes — dated to approximately 8000 BC — were found in the Tres Ventanas caves, south-east of Lima.

For the Inca Empire, the potato was not simply a crop. It was a pillar of life, with its own spiritual dimension. There was a deity dedicated to it: Axomama, the potato mother goddess. At planting time, communities held ritual ceremonies in which men used the chaquitaclla — a foot-driven farming tool still used in Andean communities today — to open the earth, while women planted the seeds. This was not agricultural production as we understand it. It was a conversation with the land.

The Andean concept behind this is called ayni: reciprocity. You give before you take. You ask permission. You thank the earth for what it provides. I find myself explaining this to Swiss friends who visit and wonder why Peruvian food tastes the way it does. Part of the answer is in that relationship — a ten-thousand-year habit of care.

Chuño: The Andean Technology That Built an Empire

Here is one of the most remarkable food technologies in history — invented not in a European laboratory but on a high plateau at 3,800 metres, using nothing but freezing nights, mountain sun, and people’s feet.

Many high-altitude potato varieties are naturally bitter or mildly toxic in their raw state. The solution developed by Andean cultures including the Tiwanaku was chuño: a natural freeze-drying process that turns a fragile crop into something that lasts for years. Potatoes are spread on the ground overnight to freeze in the sub-zero temperatures of the altiplano. In the morning, people walk over them to press out the moisture released by the ice. This is repeated over several days, alternating with exposure to sun and wind, until the potato is completely dehydrated and shelf-stable.

Chuño was the strategic food reserve that made the Inca Empire logistically possible. The Inca maintained vast storehouses — qollqas — filled with chuño distributed along the entire road network of the empire. These stores fed armies on the march, labourers building temples, and communities in years of poor harvest. You can still buy chuño in the markets of Puno and Cusco. If you come across it, try it — you are tasting a technology that has not needed to change in two thousand years.

How the Potato Changed Europe — and the World

The Spanish brought the potato to Europe around 1570, after encountering it during expeditions through the Andes — including Gonzalo Jiménez de Quesada’s 1537 expedition. Its reception was not warm. Europeans were suspicious of a plant that grew underground with no mention in the Bible, and in several regions it was classified as impure, fed to livestock, or used as a medicinal plant rather than food.

The shift came through famine and war. In France, Antoine Parmentier — a pharmacist who had survived largely on potato during his time as a prisoner of war in Prussia — became its most effective advocate. He persuaded Louis XVI to allow widespread cultivation, and convinced a sceptical public through a combination of royal endorsement and what is possibly history’s most successful guerrilla marketing campaign: he had royal potato fields planted near Paris and posted guards around them, reportedly to make people curious enough to steal the plants. Whether the full story is legend or fact, the outcome was real. The classic French potato soup still carries his name today: potage Parmentier. A French dish, named after a pharmacist, built on an Andean crop.

What to Order When You Visit Peru

If you visit Peru and only eat potatoes at tourist restaurants, you will miss everything. These are the dishes I always recommend:

Papa a la huancaína. Sliced boiled potato covered in a creamy sauce of ají amarillo, fresh cheese and milk. One of the most beloved starters in the country. Every family has a version. Try it everywhere.

Causa rellena. Yellow potato pressed with ají amarillo and lime, filled with chicken, tuna or seafood. Cold, light, and quietly brilliant — one of the most elegant dishes in Peruvian cooking.

Carapulcra. An ancestral stew made from dried potato, peanuts and various meats, with documented pre-Hispanic roots. One of the oldest continuously prepared dishes in Peruvian cuisine.

Papa rellena. Fried potato dough stuffed with a filling of minced meat, hard-boiled egg, olives and raisins. Spanish and Andean influences in every bite.

What you find when you look for native potato in Peru today

The most accessible place to encounter Peruvian potato diversity is in the markets. Any large highland market — Mercado San Pedro in Cusco, the central market in Huancayo, the Sunday market in Pisac — will have a potato section that stops most visitors in their tracks.

Ask the market vendors what the different varieties are used for and you will often get detailed, specific answers. This variety is for soup. This one is for chuño. This one is best roasted. This one must be cooked slowly. The knowledge is practical, accumulated, and still very much alive.

Several restaurants in Lima and Cusco have in recent years built tasting menus around native potato varieties — presenting five, ten, or more varieties prepared in different ways as a way of showing guests what Andean agriculture actually produced. This is worth seeking out if food is a significant part of why you travel.

Why This Changes How You Travel and Eat Peru

Knowing this story changes what you see when you travel here.

The terraced fields on the slopes above the Sacred Valley are not just scenic. They are an agricultural system designed over centuries to grow specific crops at specific altitudes — and the potato was one of the most important reasons they were built that way. The purple potato soup on a highland restaurant menu is not an exotic variation of something familiar. It is one of thousands of varieties that fed an empire and eventually fed a continent. The woman in the Pisac market with twenty types of potato in front of her is not selling a commodity. She is carrying thousands of years of agricultural knowledge that belongs to her community, her landscape, and her culture.

The potato came from Peru. When you eat it here — in any form, in any colour, at any altitude — you are eating it where it comes from. When you order a causa rellena in Lima or a bowl of chuño soup in an Andean market, you are eating something cultivated for ten thousand years before it reshaped global history. Something that, in communities at 4,000 metres, is still planted with ceremony and gratitude to the earth.

That does not change the flavour in any measurable way. But it changes the experience of eating it. And in Peru, the experience is always the point.
