Papa a la huancaína

Papa a la huancaína (literally, Huancayo-style potatoes) is a Peruvian appetizer of boiled potatoes in a spicy, creamy sauce made of queso fresco (fresh white cheese) and sautéed or grilled ají amarillo (yellow Peruvian pepper), red onion and garlic, all traditionally ground or pounded in a batán. Although the dish's name is derived from Huancayo, a city in the central Peruvian highlands nearest Lima, it has become a staple of everyday and holiday cuisine throughout the country. It is one of the most popular and representative gastronomic products of Peru.

In the south of Peru (Cuzco, Puno, Arequipa), it is served with ocopa rather than huancaína sauce, made from freshly toasted peanuts, fried onions and tomatoes, ají amarillo, cream or condensed milk, crushed crackers or dried bread, salt, and huacatay (Tagetes minuta).

While the cheese and the potato are produced along the Peruvian sierra, they are also produced along the coast. In fact, the cultivating of the yellow pepper takes place only in coastal zones (4,000-year-old yellow pepper remnants have been found in the archaeological sites of Huaca Prieta and Ancon). In addition, the olives that accompany the preparation also originate from the coast, and not the city of Huancayo. It does not match the preparation style of typical Huancan food, which often consists of hot foods made with red meat.
