Asado de picuro is a dish from the Amazon region of Peru and other parts of South America, where "picuro" refers to a species of rodent (known as the paca in English), and "asado" generally means roasted or grilled. The paca is a large rodent native to Central and South America, and it's a common source of meat in the areas where it is found.
Pacas are known for their tender and flavorful meat, which can be prepared in a variety of ways, including roasting, which is one of the preferred methods in regions where this dish is a traditional staple. The meat might be marinated with local herbs and spices and then slow-cooked over an open flame or in an earth oven, which would impart a smoky flavor to the dish.
