Guinea pigs were domesticated in the Andes thousands of years ago as a source of meat, long before they became pets elsewhere in the world.
A whole guinea pig is cleaned, seasoned, and spit-roasted or grilled over coals until the skin turns crackling-crisp, then served whole with potatoes and a peanut or chili sauce. Market stands in Pasto sell it especially during the Carnaval de Negros y Blancos festival.
