Papa pastusa is a type of potato native to the Andean region of South America, particularly in Peru and Bolivia. It is known for its unique texture and flavor, often described as creamy and slightly nutty. This potato is typically small and round, with a rough skin that can vary in color from yellow to brown. In traditional Andean cuisine, papa pastusa is commonly used in various dishes, including soups and stews. It is prized for its ability to hold its shape when cooked, making it a popular choice for recipes that require a firmer potato.
