Papa a la huancaína

Peru's ancient golden sauce: boiled yellow potatoes blanketed in a saffron-bright cream of fresh cheese, ají amarillo, garlic, and evaporated milk, served on a black olive and hard-boiled egg: the cold potato starter that has been the opening act of every Peruvian feast since the railway came to Huancayo

Origin: Peru

From the journey of Potato.

Papa a la huancaína (potato in the style of Huancayo) is one of Peru's most beloved dishes and the quintessential expression of the Andean kitchen's genius with the potato. The dish takes its name from the city of Huancayo in the Junín region of the central Andes, and according to tradition it was first prepared by women vendors (huancaínas) who sold food to workers and passengers along the Lima–Huancayo Central Railway, opened in 1908. The railway connection between the coast and the highlands created the first systematic exchange of ingredients between Lima's coastal kitchen and the Andean interior, and the huancaína sauce, made from the ají amarillo (yellow chilli) of the Amazon foothills, fresh white cheese (queso fresco), and evaporated milk, was the result of this encounter. The potato used is the yellow-fleshed papa amarilla, the most prized of all Andean potato varieties, with a naturally waxy, dense, buttery flesh that holds the sauce without crumbling. Papa a la huancaína is always served cold, as a first course, on a bed of lettuce with a hard-boiled egg and black olives: a combination whose simplicity conceals extraordinary flavour balance.

Ingredients

Potato

800 g waxy yellow-fleshed potatoes (papa amarilla if available; Yukon Gold is the best substitute)

Sauce

200 g queso fresco (fresh white cheese) or feta (rinsed to reduce saltiness)
3 ají amarillo chillies: fresh, jarred paste (3 tbsp), or frozen
100 ml evaporated milk
2 tbsp neutral oil (sunflower or vegetable)
2 cloves garlic, roughly chopped
4 crackers soda crackers or cream crackers (3–4 crackers: traditional thickener)

Seasoning

1 tsp salt (or to taste)

Garnish

4 eggs, hard-boiled and halved
8 black olives
Lettuce leaves (butter lettuce or iceberg), to serve

Method

Boil the potatoes in their skins in well-salted water until completely tender: a skewer should pass through without resistance. Drain and allow to cool slightly, then peel. Keep warm.
If using fresh ají amarillo, roast them briefly over a gas flame or under a hot grill until the skin blisters. Peel, slit, and remove the seeds and membranes (which carry most of the heat). If using jarred ají amarillo paste, measure out 3 tablespoons.
Blend the queso fresco, ají amarillo (or paste), evaporated milk, oil, garlic, and crackers in a blender until completely smooth and creamy. The sauce should be pourable but thick enough to coat a spoon generously. Season with salt.
Arrange lettuce leaves on a serving plate. Slice the warm potatoes and lay over the lettuce. Pour the huancaína sauce generously over the potatoes, completely blanketing them.
Garnish with the halved hard-boiled eggs, black olives, and optionally a sprinkle of dried red chilli or a few fresh coriander leaves. Serve immediately as a cold first course.

Notes

Peru has an extraordinary relationship with the potato: over 3,000 native varieties are cultivated in the Andean highlands, more than anywhere else in the world. The International Potato Center (Centro Internacional de la Papa, CIP) is based in Lima and maintains the world's largest potato germplasm bank (a collection of over 4,000 potato varieties, including wild species. The papa amarilla) with its yellow-orange flesh, buttery flavour, and dense, waxy texture: is considered the finest of all for cold preparations and is the potato that defines the Peruvian cuisine's most celebrated dishes. It is rarely available outside Peru and neighbouring Andean countries.
