The story
Caldo de piedra comes from San Felipe Usila, a Chinantec village in the river country of northern Oaxaca, in the Papaloapan basin. Villagers believe it dates from before the Spanish conquest. Traditionally the men make it on the riverbank at the end of a day's fishing: fish and shrimp go into a gourd bowl or rock hollow with water, tomato, chilli, onion and herbs, then stones heated red-hot in a fire bring it to a boil in moments. Over time it became a meal the men prepare to honour the women of the community. Restaurants in Oaxaca city and beyond have since carried it further.
Also known as sopa de piedra, caldo de piedra de Usila.
