Papa a la huancaína means potatoes in the style of Huancayo, a city in the central Peruvian highlands, though where the dish was really born is argued over, and Lima claims a share of it too. What nobody argues about is its place on the table: it is one of the most popular and representative dishes in Peru, served as a starter at home, in cevicherías and at family celebrations, and packed for picnics and journeys because it is eaten cold.
The sauce is the heart of it. Ají amarillo, the fruity, golden-orange Peruvian chili, is sautéed with a little onion and garlic and then blended with queso fresco, evaporated milk and a few saltine crackers until thick, smooth and pale yellow; traditionally it was ground on a batán, a flat grinding stone. It should coat the potato like a thick custard, with gentle heat rather than fire.
Peru's yellow potatoes, papa amarilla, are boiled, cooled and sliced thick onto lettuce leaves, covered in sauce, and finished with hard-boiled egg and a few purple botija olives.

Ingredients
US
Metric
Serves 4
- 6 medium (about 1 kg) yellow potatoes (papa amarilla) or Yukon Gold
- 2 tbsp vegetable oil
- 3 tbsp ají amarillo paste, or 3 fresh ají amarillo, seeded, veined and chopped
- 1/4 small onion, roughly chopped
- 1 clove garlic
- 200 g queso fresco (fresh white cheese), crumbled
- 3/4 cup evaporated milk
- 4 saltine crackers
- to taste salt
- 4 large lettuce leaves
- 2 hard-boiled eggs, quartered
- 8 black botija olives (or Kalamata)
Instructions
- 1Boil the potatoes in well-salted water for 20 to 25 minutes until tender but not falling apart. Drain, let them cool, then peel them.
- 2Heat the oil in a small pan and gently fry the ají amarillo, onion and garlic for 3 to 4 minutes until soft.
- 3Tip the mixture into a blender with the queso fresco, evaporated milk, crackers and a pinch of salt, and blend until completely smooth.
- 4Check the texture: it should be thick and pourable, like a custard. Add a splash more milk to thin it or another cracker to thicken it, then taste for salt.✎ Chef’s noteThe crackers are a thickener, not a flavour. Add them one at a time until the sauce clings to a spoon.
- 5Lay a lettuce leaf on each plate, arrange thick slices of potato on top and cover them generously with the sauce. Garnish with egg quarters and olives and serve cold or at room temperature.

📍
Lima. Causa is Lima's, layered cold from yellow potato mashed with lime and aji amarillo around a filling of chicken, tuna or crab. Its name is said to come either from selling it por la causa to fund San Martin's campaign or from women feeding soldiers during the Pacific War, and neither account is settled. Picarones, squash and sweet-potato rings in chancaca syrup, are the colonial answer to Spanish bunuelos.
🗺️
Peru. The Andes are a working farm at altitude. The International Potato Center in Lima counts more than four thousand native potato varieties across the highlands of Peru, Bolivia and Ecuador, each selected over generations for a particular soil and frost line, and the same cold that limits what will grow is put to work preserving it as freeze-dried chuno.
🌍
South America. South America's cooking follows its dramatic geography, potatoes and quinoa in the high Andes, cassava and river fish in the Amazon basin, and grass-fed beef on the pampas. Indigenous ingredients like maize, ají peppers, and cacao meet Spanish, Portuguese, African, Italian, and Japanese influences brought by five centuries of migration. Ceviche, feijoada, arepas, and the smoke of the asado are its most beloved icons.
The story behind this dish is up top, worth a read while the pot works.
