Curanto (from Mapudungun: kurantu 'stony') is a traditional Chilote method of cooking food using heated rocks buried in an earth oven that is covered with pangue leaves and turf.
The fundamental components are seafood, potatoes, along with other traditional preparations from Chiloé Archipelago such as milcao and chapalele, to which are added meats, sausages and sometimes crustaceans.
[1][2][3] It is part of the Chilean cuisine, and it is one of the most recognized dishes of traditional Chilote cuisine whose oldest archaeological remains dates to more than eleven thousand years before present on the Greater Island;[1] there are also finds of lesser data in areas of the coastal edge of the Reloncaví Sound, the inland sea of Chiloé and the northern Patagonian channels.
All this is covered with wet sacks, and then with dirt and grass chunks, creating the effect of a giant pressure cooker in which the food cooks for approximately one hour.
It is believed that this form of preparing foods was native to the "chono" countryside and that, with the arrival of the southern peoples and the Spanish conquistadors, new ingredients were added until it came to be the curanto that is known today.
