Originated in southern Peru in the Arequipa province, Salsa Ocopa is similar in texture to Salsa Huancaina and traditionally as well served with boiled potatoes. But its flavour is very different. The main ingredient of Salsa Ocopa is the herb Huacatay (Peruvian black mint) which gives the sauce a really unique delicious taste. Other ingredients include fresh white cheese (queso fresco), onions, aji amarillo (Peruvian yellow chilli) and milk.
