Note sull'episodio
Ceviche looks cooked, but it never touches heat. This episode explains how citric acid denatures fish proteins, turning translucent flesh opaque and firm, and why that chemical costume does not sanitize food. Acid marinades do not kill parasites such as Anisakis or pathogens like cholera, which is why health authorities have warned pregnant women to avoid the dish.
We then trace ceviche from proto-ceviche cultures such as Caral in Peru and Valdivia in Ecuador, through Moche use of fermented tumbo and Inca use of chicha, to the Spanish arrival of limes, onions, and escabeche. Along the way we unpack the debated etymology, the Nikkei chefs who shortened marination to minutes in the 1970s, regional variations across Latin America, and Peru's 2023 UNESCO recognition.
