Caldo de Piedra
Also known as: Caldo de piedra, Caldo de Piedra Oaxaqueño
Chinantec hot-stone broth with locally documented tadpoles, tomato, onion, chilli and wild coriander.

About Caldo de Piedra
This Caldo de Piedra represents the Santa Cruz Tepetotutla preparation documented by Flores, Arreortúa and González-Bernal. Their field study records a local Chinantec version using Duellmanohyla ignicolor tadpoles during the seasonal tradition.
Tomato, onion, chilli and wild coriander provide the vegetable and herbal seasoning, with salt in the broth. Interviewed residents describe the tadpoles as having a fish-like flavour.
The tadpoles and vegetables sit in a liquid broth within a bowl. Heated stones are the cooking medium in this specific regional preparation, rather than an ordinary stove-heated pot.
